    摘 要:針對傳統(tǒng)模糊控制器在控制過程中存在超調(diào)量大、控制精度不高以及靜差等問題,提出了一種基于優(yōu)化模糊自適應 PID 的開關磁阻電機控制方法。利用改進蝙蝠算法對模糊控制器進行優(yōu)化,以外環(huán)模糊自適應 PID 控制器的輸出變量為內(nèi)環(huán)控制系統(tǒng)的參考轉矩,送入直接轉矩控制系統(tǒng)。仿真結果表明,經(jīng)過算法優(yōu)化的模糊自適應 PID 控制器在動態(tài)性能和魯棒性方面明顯優(yōu)于傳統(tǒng)模糊 PID 控制器,成功克服了模糊控制中存在的穩(wěn)態(tài)誤差和抗干擾能力不足的問題,有效解決了系統(tǒng)上升時間和超調(diào)之間的矛盾,同時顯著減少了電機轉矩的脈動。

    Abstract: Aiming at the traditional fuzzy controllers in the control process, there were problems such as large overshoot, low control accuracy and static error, a switching reluctance motor control method based on optimize fuzzy adaptive PID was presented. The fuzzy controller was optimized by using improved bat algorithm, and the output variables of the outer loop fuzzy adaptive PID controller is the reference torque of the inner loop control system, which is sent to the direct torque control system. The simulation results showed that the algorithm-optimized fuzzy adaptive PID controller is significantly better than the traditional fuzzy PID controllers in dynamic performance and robustness. It successfully overcomed the problems of steady-state errors and insufficient anti-interference capabilities in fuzzy control, and effectively solved the contradiction between the system rise time and overshoot, and at the same time significantly reduced the pulse of the motor torque.
    Key words: switched reluctance motor; fuzzy adaptive PID; improved bat algorithm; direct torque control
