A frequency domain design of PID controller for an AVR system

引用

Journal of Zhejiang University-Science C(Computers and Electronics) 2014年第4期15卷 293-299页

作者： Md Nishat anwar Somnath PAN Department of Electrical Engineering Indian School of Mines

We propose a new proportional-integral-derivative(PID) controller design method for an automatic voltage regulation(AVR) system based on approximate model matching in the frequency domain. The parameters of the PID controller are obtained by approximate frequency response matching between the closed-loop control system and a reference model with the desired specifications. Two low frequency points are required for matching the frequency response, and the design method yields linear algebraic equations, solution of which gives the controller parameters. The effectiveness of the proposed method is demonstrated through examples taken from the literature and comparison with some popular methods.
