本文首先从系统模型结构着手,结合自校正控制和解耦控制在控制目标函数中引入对解耦控制的要求,提出了一种新的多变量自校正控制方法。从而使控制系统既具有渐近最优性;又具有解耦性。本文有效地解决了非最小相位系统的控制问题。最后,对高温扩散炉进行了多变量解耦自校正的实时控制,并取得了良好的控制效果。 In this paper, a new multivariable self-tuning control method is proposed based on the model structure of the system. The self-tuning control and decoupling control are introduced into the control objective function to control the decoupling control. So that the control system has both asymptotic optimality and decoupling. This paper effectively solves the control problem of non-minimum phase system. Finally, real-time control of multivariable decoupling self-tuning was carried out on high-temperature diffusion furnace, and a good control effect was obtained.
