Abstract : "This paper studies the tracking control of dc permanent magnet motor (DC-PMM) in networked control
systems (NCSs) with random delay and packet dropouts in feedback channel (sensor to controller) and the feedforward
channel (controller to actuator). A sliding mode predictive tracking control algorithm based on the theory of
pseudo partial derivative (PPD) is designed to compensate random delay and packet dropouts in process of motor
control. The stability of the proposed method and the convergence of the tracking error are analyzed and proved.
Finally, an example about dc motor in NCS is given to verify the effectiveness of the proposed method. Simulation
results show that the outputs of dc motor can better track the desired trajectory after compensating by the presented
method, and are quite stable."
