The document describes an experiment to validate a novel controller called a Piecewise Predictive Estimator (PPE) that aims to increase the frequency response of an aerospace electro-mechanical actuator (EMA) by reducing phase lag. The experiment showed that combining a PID controller with PPE increased the EMA's bandwidth from 22Hz to 25Hz without increasing noise levels, validating that PPE successfully enhances EMA performance by reducing phase lag at higher frequencies. The document also provides background on EMA modeling and design challenges, and discusses PID, LQR, and PPE controller design approaches.
