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.

The purpose of the field-oriented control (FOC) is therefore to create a tool that allows the decoupling control of the flux and torque-producing current components from the three-phase AC currents flowing in the coil. The FOC drive system is a system based on the principle of decoupling the above power components thanks to the stator current feedback control (the innermost circuit of the drive system). The FOC-type control method belongs to the class of vector control methods for electrical machines.

In this study, a control system is proposed for the induction servomotor to achieve the highprecision speed tracking based on wavelet fuzzy cerebellar model articulation controller. In this proposed scheme, the wavelet fuzzy cerebellar model articulation controller (WFCMAC) is used to imitate an ideal controller due to it incorporates the advantages of the wavelet decomposition property with a fuzzy CMAC fast learning ability and the smooth compensator controller with bound estimation is designed to attenuate the effect of the approximation error caused by the WFCMAC approximator.
