This study presents an application of a fuzzy gain scheduled proportional and integral (FGPI) controller for load-frequency control of a two-area electrical interconnected power system. Model simulations of the power system show that the proposed FGPI controller is effective and suitable for damping out oscillations resulted load perturbations.

单相全桥PWM整流模型，多次验证表明，该模型动态响应快，静态误差小，完全符合要求。(The single-phase full bridge PWM rectifier model, verified the model many times, fast dynamic response, static error is small, fully meet the requirements.)
