Abstract :

This paper proposes design of proportional-plus-integral-plus-derivative (PID) controllers for a linear and nonlinear static compensator (STATCOM) model using Ziegler Nichols (ZN) tuning method. The design is further extended to a nonlinear fuzzy-proportional-plus-derivative (FPD) control scheme. Comparison between the crisp PI, crisp PD, and Fuzzy PD was simulated in Matlab/Simulink environment with varying circuit parameters such as resistance, inductance, and capacitance for the linear and nonlinear setup. The results showed that the FPD is more robust in handling those changes against its counterparts. The study is particularly important in determining the choice of a control regime for solving power quality (PQ) problems in the advent of a smart grid.
