摘要
针对感应电动机运行过程中负载变化及升温引起的转子电阻变化,采用基于参数描述符法描述系统,并将系统稳定和性能问题转化为一个标准的H∞控制问题。通过求解线性矩阵不等式组,实现系统鲁棒稳定和满足系统性能要求的输出反馈控制器。仿真结果表明,控制器不仅使系统具有良好的鲁棒性,同时提高了系统的调速性能。
Focused on dealing with the uncertainties of load and the rotor resistance during operation, introduced the description form representation to describe the system and converted the robust stability and performance of the system into the standard H∞ control problem. Based on robust control theory, a feedback controller, which satisfied performance of the system, was designed with a linear matrix inequality approach. Simulation results demonstrated that the controller was robust as well as the perform- ance of the system.
