具有降阶模型的多变量鲁棒自适应前馈控制器

本文提出了一种多变量鲁棒自适应前馈控制器。该控制器采用低阶模型来控制参数未知的高阶多变量系统时,在可测干扰和有界不可测干扰作用下能保证自适应系统稳定运行。当可测干扰与系统输出之间存在未建模动态时,它可以对可测干扰实行有效的动静态补偿。当只有有界干扰作用时,它能使有界干扰对系统产生的影响最小。本文还给出了采用所提出的控制器控制某钢厂间歇式余热锅炉的仿真结果。

A Multivariable Robust Self-Tuning Controller with Feedforward

In this paper, a multivariable robust self-tuning controller with feedforward is presented. The con-troller can ensure the stability of the adaptive systems affected by measurable disturbances and bounded distur-bances. When it uses low order model to control the high order systems with unknown parameters. It can effec-tively compensate the measurable disturbance both dynamically and at static state in presence of the unmodelled dy-namics between measurable disturbances and system outputs. It can minimize the effect of the bounded disturbance on system outputs in the presence of bounded disturbances. The simulation results for robust adaptive feedforward control of an intermittent afterheat furance is also given in this paper.
