高压断路器直线伺服电动机操动机构采用直线电动机驱动断路器操作杆,带动机构运动,实现分合闸操作,具有良好的快速响应能力及控制性能。本文建立了直线伺服电动机操动机构控制系统仿真模型,详细分析了单神经元PID控制算法以及数学模型,并建立了以输出误差二次方为性能指标的单神经元自适应PID控制器模型。分别用传统PID控制与单神经元PID控制,对高压断路器触头运动特性控制过程进行了仿真。结果表明,单神经元PID控制器能够较好地实现触头速度的跟踪控制,使其按给定运动特性曲线运动,实现运动特性控制。证明了在配有直线伺服电动机操动机构的高压断路器触头运动控制系统中,单神经元PID控制是一种较理想、有效的控制方法。

Single neuron PID （Proportional Integration Differential） controller used in high voltage circuit breaker linear servo motor operating mechanism is designed. Operating arm driven by linear-servo motor realizes the opening and closing operation, by which the quicker response ability and the better performance can be obtained. Then the control system simulation model of linear servo motor operating mechanism is developed. Control algorithm of single neuron PID and its mathematical model are discussed in detail. A single neuron PID controller mathematical model is formed by taking values of output error square as performance index. Traditional PID and single neuron PID simulation are used separately in the analysis of moving contact movement control during the opening and closing of the high voltage circuit breaker. Test results show that single neuron PID control strategy can achieve the speed tracking, improve the effectiveness of the control, and make the movement curve same as the defined one. This control strategy is a better one for contact movement control to high voltage circuit breaker.
