摘要
基于二次调节加载试验台系统,针对二次调节转速控制系统存在模型参数不确定性以及力矩扰动,通过选择合适的加权函数将二次调节转速控制转化为H∞混合灵敏度问题。建立了二次调节转速控制系统数学模型,并采用H∞优化方法设计了鲁棒控制器。最后对二次调节转速控制系统进行了仿真研究,结果表明采用鲁棒控制器的转速系统较传统的PID控制的控系统具有更好的鲁棒稳定性和抗干扰性能。
Based on the loading test-bed of secondary regulation system, for the model parametric uncertainty and the torque disturbance of the secondary, regulation speed control system, the speed control problem was converted into an H∞ mixed sensitivity problem through choosing suitable weighting functions. The mathematic model of the speed control system was build, and the controller was designed by H∞ optimization. The secondary regulation speed control system was studied by simulation. The results show that the robust stability and the disturbance rejection performance of the speed control system with the robust controller are much better than that with PID controller.
