In this paper, we propose PID controller with feedforward current low pass filters (FLPFs) to improve the position and currents tracking performances. The position
controller consists of a PID controller, a commutation
scheme, and a Lyapunov-based controller. PID controller
is used to generate desired torque [10]. Commutation
scheme is used to transform the desired torque into the
desired currents. Lyapunov-based controller (LBC) is designed to guarantee the desired currents [8]. The FLPFs
are proposed to reduce measurement noises and compensate to the phase lag due to the conventional LPFs.
The closed-loop stability is proven using Lyapunov theory. Simulations were performed to evaluate the proposed method.
