Design of Fractional-Order PID Controller for Vector-Controlled Induction Motors
نویسندگان
چکیده
The main objective of this paper is to design a fractional-order PID speed controller for vector-controlled induction motors, where possible parameter variations and load disturbances are considered. The required parameters of the fractional-order PID controller can be obtained by utilizing the Matlab optimization toolbox, in which phase margin, gain-crossover frequency, high-frequency noise rejection and low-frequency disturbance rejection are the performance of concern. In addition to the simulations, a DSP/FPGA-based experimental platform is used for experiment verification. From simulation and experimental results, compared to the conventional PID controller, the proposed robust fractional-order PID controller can provide better control performance subject to parameters variations and load disturbances. Key-Words: Fractional-order PID controller, Vector control, Induction motor, DSP/FPGA
