摘要：
An improved technique for controlling an electro-mechanical actuator combines a sliding mode of control with a second mode of control. An error signal is generated based on the difference between an input position signal and a feedback position signal. When the error signal is above a predetermined threshold, the actuator is controlled in the sliding control mode. When the error signal is below the predetermined threshold, the actuator is controlled in the second control mode. The combination of the sliding control mode with the second control mode yields a robust controller that can tolerate large parameter variations and uncertainties without sacrificing precise steady state tracking.
