摘要:

根据预测控制思想,针对已有的电液伺服调速系统模型,设计了一种基于前馈预测的PID控制系统。该控制系统不依赖对象的精确数学模型,利用预测控制的快速性以及自适应性等特点,通过滚动优化与PID相结合来确定系统当前时刻的控制量。仿真实验结果表明,该文建立的新型控制器能够满足现有的电液伺服调速系统的控制性能要求,实现对该系统的快速精确控制。

Abstract:

A PID control system based on feedforward prediction was designed according to the thought of predictive control, in view of the existing model of electro-hydraulic servo control system.. The control system does not rely on the exact mathematical model of the object, and uses the characteristics of the fast and adaptive predictive control to determine the current control of the system by the combination of rolling optimization and PID. The simulation results show that the new type of controller can satisfy control performance requirements of the existing electro-hydraulic servo control system, achieving the rapid precise control of the system.
