Fuzzy-PID controller optimized TLBO approach on automatic voltage regulator

A Fuzzy Proportional-Integrator-Derivative (PID) has been put forward in aforementioned paper. Tuning of FLC is done using three met heuristics algorithm namely PSO, FA & TLBO to actuate the different parameters of PID controller in AVR system. The objective function applied in the model is ITAE as well as controller optimum gain is also inherited. TLBO approach FPID controller shows better transiency response. A discrete-time form of conventional PID controller is Fuzzy PID. Load variation of time constants are done in range of [- 5C%+ 5C%]to verify the robustness.
