This paper presents a method to design a time-varying parameter PID controller for Bézier trajectory tracking of a differential-drive mobile robot (DDMR). First, the robot's linear error model is established by linearizing around the desired angular velocity of the nonlinear kinematic error model. Then, the variable parameter PID controller is designed to control the DDMR to follow the Bézier trajectory with minor error under the condition of time-varying velocity.

With a classic Proportional-Integral-Derivative (PID) control, the trajectory tracking performance is not high because a fixed set of PID parameters does not solve the enhancing performance problem. Therefore, in this paper, a fuzzy PID control (FPIDC) for a PAM is presented to improve the trajectory tracking performance. The efficiency of the proposed controller has been verified by experiment under different conditions.

This study presents a force control approach for an EHA system using a combination of a feedforward-based PID (FPID) controller and a grey predictor (GP), shortened as grey predictor-based feedforward PID Controller (GPFPID). The FPID controller is used to drive the system to desired targets. Meanwhile, the GP predictor takes part in estimating the output in the near future to optimize the controller parameters in advance and to create a compensating control signal corresponding to the system perturbations, consequently, improving the control performance.
