Shrimanth Sudheer, Immanuel J., P. Bhaskar, and Parvathi C. S. Department of Instrumentation Technology, Gulbarga University Post Graduate Centre, RAICHUR –584133, Karnataka, INDIA, ABSTRACT Design and construction of a microcontroller based liquid level control system is presented in this paper. ARM7 (Philips LPC2129) microcontroller based system for the real time liquid level control is developed using the fuzzy logic controller (FLC). This controller has been applied to the water-in-tank level control of a continuous process. The controller is implemented in embedded C language to control the liquid level to the desired value. The performance of the proposed controller is compared with conventional PID controller. An accuracy of ±.1% is achieved in the control of liquid level over the range of 0 to 100cm. It is observed that the proposed scheme controls the tank level effectively not only in the steady state but also in the transient state. Keywords: ARM7, FLC, Liquid Level, Microcontroller. 1. INTRODUCTION The nonlinear systems are frequently encountered in the process industries. Level of liquid being an important process parameter has to be maintained at the desired level for smooth running of the process and for better quality products. There have been many papers reported on the subject of controlling and monitoring liquid level in different industrial processes. M. Wang and F. Crusca [1] designed and implemented a gain scheduling controller for water level control in a tank. It was observed that the system achieved a better performance over the conventional controllers like P, PI, and PID. W. Zhang et al [2] proposed a new two-degree-of-freedom level control scheme for processes with dead time T. Heckenthaler and S. Engell [3] developed level controller for a nonlinear two-tank system based on fuzzy control. Similarly, application of fuzzy logic for water level control of small- 217

International Journal of
Electronics and Communication Engineering & Technology (IJECET), ISSN 0976 – 6464(Print), ISSN 0976 – 6472(Online) Volume 4, Issue 2, March – April (2013), © IAEME scale hydro-generating units was reported by T. Niimura and R. Yokoyama [4]. The recent work by W. Chatrattanawuth et al [5] reported a level control system using a fuzzy I-PD controller. Their simulation results shown that fuzzy I-PD controller performed better over conventional controller. C. Li and J. Lian [6] reported the application of genetic algorithm in PID parameter optimization for level control system. They simulated the proposed strategy on MATLAB and later tested using LabVIEW. Another LabVIEW based water level control is also reported by L. Gao and J. Lin [7]. The DCS based water level control of boiler drum is reported by Y. Qiliang et al [8]. A similar work is also reported by H-M Chen et al [9]. They designed a sliding mode controller for a water tank liquid level control system. Few authors reported various schemes and their implementation on different platforms such as PC/uP/DSP. Some of the reports were also based on simulation. But an attempt is made here to implement a fuzzy logic control algorithm on a microcontroller for real time level control of a water-in-tank system. This approach will reduce the cost and space of the system. We will address this issue by employing an advanced ARM7TDMI (PHILIPS LPC2129) processor. 2. DESIGN OF FUZZY LOGIC CONTROLLER As the name itself suggests, a fuzzy logic controller incorporates fuzzy logic for decision making or rather to produce control action as required by the plant or process [10]. FLCs are knowledge based controllers consisting of linguistic “IF-THEN” rules that can be constructed using the knowledge of experts in the given field of interest. A two input and one output fuzzy logic controller is designed as shown in the Fig. 1. The error (e) and change-in-error (ce) are the two inputs, and control action (ca) is the corresponding output of the FLC. A triangular membership function with seven members (linguistic variables) termed as negative large (NL), negative medium (NM), negative small (NS), zero error (ZE), positive small (PS), positive medium (PM), and positive large (PL) are used to map the crisp input to universe of discourse (-1 to +1). The universe of discourse is the range over which the fuzzy variables are defined. The control rules are constructed to achieve the best performance of the FLC. With seven members, we obtain 49 rules. Mamdani inference engine is used [11]. The e input to the controller is obtained by subtracting measured value/process variable (y) from the reference (r), and the ce is difference between present and previous errors. The output of the controller i.e., change in control action (ca) is applied to the process. The r, which is also the desired value, is entered by the operator in the beginning. This is a closed loop control where the process variable is continuously monitored to maintain the error to zero.

ARM7 MICROCONTROLLER BASED LEVEL CONTROL SYSTEM The block diagram of proposed fuzzy logic controller scheme for liquid level control system is illustrated in Fig. 2. A cylindrical tank of 100cmX20cmX20cm dimension is considered. Level of the liquid (water) contained in a tank is measured and controlled at the desired value. The level is measured in terms of pressure developed in the capillary attached to the tank at the bottom. As the liquid level in tank increases the pressure developed inside the capillary also increases. Hence, the pressure, directly proportional to the liquid level, is sensed and converted into equivalent voltage by the integrated circuit differential pressure transducer (DPT) placed on the top of the tank. The microcontroller measures the liquid level through this sensor, signal conditioner, and on-chip analog to digital converter (ADC) and displays it on LCD in terms of cm. The inlet flow of water from a pump (motor) to the tank is controlled by a pneumatic control valve (PCV) which in turn controlled by the microcontroller through on-chip PWM unit, PWM to voltage converter, V/I converter, and current to pressure converter (IPC). The PWM technique is employed to precisely move the pneumatic valve.

It is basically an integrated circuit differential pressure transducer (DPT) consists of four strain gauges connected in Wheatstone bridge and are pasted on a diaphragm. The bridge is excited with a stable +5V DC. The sensor is provided with two input ports for applying either single ended or differential pressure. In this application, one port is closed, and another is connected to the bottom of the tank for single ended measurement. The input change in pressure, exerted on the diaphragm, is converted into corresponding change in resistance which is further converted to change in voltage. 4.3 Excitation Source In order to convert the change in resistance of the sensor to the corresponding change in voltage, a precise and constant excitation voltage of +5V is generated using LM329, LM308, and 2N2222 as shown in Fig. 4. LM329, a precision voltage source, produces 6.9V which is dropped down to +5V and connected to non-inverting terminal of op-amp LM308. An op-amp with npn-transistor 2N2222 at the output provides the enough current to the bridge. With a +5V excitation voltage, the sensor will produce an output of 1.5mV/cm. An offset-nullify circuit, using a potentiometer, is connected to bridge output to nullify the offset and make zero adjust in initial condition. 4.4 Instrumentation Amplifier Sensor produces a small differential output voltage of 1.5mV/cm liquid height. So an instrumentation amplifier, AD620 [14] from Analog Devices, is used to pick, amplify, and convert it to single ended voltage compatible to be sampled by the on-chip ADC of LPC2129 microcontroller. A gain of 10 is set for the instrumentation amplifier to get 15mV/cm which is more than the resolution of ADC. 220

RESULTS The real time implementation of FLC for liquid level control is tested for standard step input of 15 cm. A step input from initial value of 0 cm is applied to the controller. The performance of FLC is compared with the conventional PID controller for the same step of 15 cm. The plots in Fig. 6 show step input response of FLC and PIDC. It is evident from the plot that FLC performs superior over PIDC in terms of sharp rise time, and quick settling time.

CONCLUSION In this paper we have successfully designed and implemented a fuzzy logic controller on ARM7 microcontroller for a real-time liquid level control. The real time experimental results show that the proposed control scheme provides better transient as well as steady state response. More remarkably, the error response seems to be excellent in contrast to most available linear PID controller. Besides, the incorporation of ARM7 microcontroller made the system very compact and low cost. REFERENCES [1] M. Wang and F.
