        摘 要:針對傳統(tǒng) PID 控制在永磁同步電機控制系統(tǒng)中未能實現(xiàn)精準控制的問題,提出了一種基于改進蜣螂優(yōu)化算法的 BP 神經(jīng)網(wǎng)絡(luò) PID 控制器,該控制器由 BP 神經(jīng)網(wǎng)絡(luò)通過自適應(yīng)方法來調(diào)整權(quán)重系數(shù),解決了 PID 無法在線調(diào)節(jié)參數(shù)的缺點。針對 BP 神經(jīng)網(wǎng)絡(luò)在進行反向傳播時陷入局部最優(yōu)的概率較大,引入蜣螂優(yōu)化算法通過適應(yīng)度值不斷更新 BP 神經(jīng)網(wǎng)絡(luò)核心參數(shù),從而提高 BP 神經(jīng)網(wǎng)絡(luò)的優(yōu)化速率。對于蜣螂優(yōu)化算法中存在初始種群質(zhì)量不高及搜索能力不足等問題,對蜣螂優(yōu)化算法進行混合策略優(yōu)化,大大提升了蜣螂優(yōu)化算法求解效率和精度。實驗結(jié)果表明該改進蜣螂優(yōu)化算法可以有效地提高控制系統(tǒng)的響應(yīng)速度,減小超調(diào)量,在轉(zhuǎn)速和負載突變的情況下都有較強的魯棒性。

        Abstract: In view of the problem that traditional PID control fails to achieve accurate control in the permanent magnet synchronous motor control system, a PID controller of BP neural network based on improved dung beetle optimization algorithm is proposed. The controller uses BP neural network to adjust the weight coefficient by adaptive method, which solves the shortcoming that PID can not adjust parameters online.Then, aiming at the high probability of BP neural network falling into local optimum when performing back propagation, the improved dung beetle optimization algorithm is introduced to continuously update the core parameters of the BP neural network through the adaptive value, so as to improve the optimization rate of the BP neural network. Furthermore, addressing issues like low initial population quality and inadequate search capability in the improved dung beetle optimization algorithm, a hybrid strategy is implemented to optimize the improved dung beetle optimization algorithm, which greatly improves the solving efficiency and accuracy of the improved dung beetle optimization algorithm. Experimental results demonstrate that the improved dung beetle optimization algorithm effectively enhances the response speed of the control system, reduces overshoot, and it has strong robustness to the case of speed and load sudden change.
        Key words: permanent magnet synchronous motor; improved dung beetle optimization algorithm; BP neural network; PID control
