摘要:

针对由一系列环节串联而成且存在多种约束的复杂工业对象,利用过程的中间变量进行预测和反馈,在充分考虑控制量幅值约束、控制增量幅值约束、中间变量幅值约束、输出误差约束以及最终输出幅值约束共同构成的多约束情况下,提出了工业串联系统的多约束广义预测控制算法。仿真结果验证了该算法对多约束串联系统的有效性和较强的鲁棒性。

Abstract:

A multiple constrained generalized predictive control algorithm for cascade industrial systems is presented by considering fully of the amplitude constraints of inputs,the amplitude constraints of input increments,the amplitude constraints of internal variables,the amplitude constraints of outputs and the constraints of output errors.It uses internal variables for prediction and feedback.The simulation results show that the control algorithm is robust and works effectively for multiple constrained cascade industrial systems.
