摘　　要：为实现采煤机滚筒位置精确调整,建立了滚筒位置控制系统开环传递函数,基于Simulink搭建了采煤机滚筒位置仿真模型,分别采用果蝇算法和Ziegler-Nichols算法对PID控制器参数进行优化,对系统施加不同信号模拟采煤机实际工况,研究了两种算法对滚筒位置控制性能的优化效果。结果表明:基于果蝇算法优化的系统阶跃响应超调量、调整时间、稳态误差等指标均减小,系统正弦响应平均跟踪误差缩小45%以上,系统随机响应曲线波动范围均减小,因此基于果蝇算法优化的系统在工况变化时具有较强的鲁棒性。In order to achieve precise adjustment of the position of shearer drum,the drum to establish a position control system open loop transfer function,based on the position of the drum shearer built Simulink simulation models,algorithms and drosophila respectively Ziegler-Nichols algorithm to optimize the parameters of the PID controller,different signals applied to simulate actual working conditions to shearer system to study the effects of two optimization algorithms roller position control performance,results show that:Drosophila optimization algorithm based system step response overshoot,settling time,steady error of state indicators are reduced,the average system response to the sinusoidal tracking error reduced more than 45%,the system randomly reduced when the fluctuation range of the response curve,it has robustness when operating conditions change Drosophila optimization algorithm based system.
