精校机电液位置伺服系统的广义预测控制

摘要

The discrete mathematical modal of electro-hydraulic position servo system for precise straightening press was built.A method of general predictive control of the electro-hydraulic position servo system of the precise straightening press was presented by applying theory of general predictive control.The simulation result shows that control precision and tracking performance of the system are improved greatly.%建立精密校直液压机(精校机)电液位置伺服系统离散数学模型,将广义预测控制理论应用于精校机电液位置伺服系统中,提出精校机电液位置伺服系统的广义预测控制方法.仿真结果表明,系统的跟踪性能良好、控制精度提高.
