    摘 要:根据高压断路器电机操动机构运动过程非线性特点,提出模糊 PI 控制方法,可随时更改控制参数来适应断路器不同运动状态。介绍了操动机构的动触头运动原理和系统控制原理;在 Simulink 环境下采用模糊 PI 控制方法,建立基于无刷直流电机系统的控制仿真模型,同时对模型进行分析。仿真结果表明,运用模糊 PI 控制方法,动触头速度与给定速度的误差较小,超调量较低,速度曲线响应迅速,实现对高压断路器动触头的准确控制,可运用到电机操动机构运动控制系统。

    Abstract: This paper proposed a fuzzy PI control method, which can change the control parameters at any time to adapt to the different motion states of the circuit breaker based on the nonlinear characteristics of the moving process of the high-voltage circuit breaker motor operating mechanism.It introduced the moving contact movement of the operating mechanism theory and the system control theory. This paper used the fuzzy PI control method to establish a control simulation model based on the brushless DC motor system under the Simulink condition and analyzed the model.The simulation results show that using the fuzzy PI control method, the error between the moving contact speed and the given speed is small, the overshoot is low, and the speed curve responds quickly. It can achieve accurate control of the moving contact of the high-voltage circuit breaker, which can be applied to the motor operating mechanism motion control system.
    Key words: high-voltage circuit breaker; motor operating mechanism; brushless DC motor; fuzzy PI control
