本文针对多变量系统提出了一种新的多环预测自整定PID控制器设计方案。该方案首先使用静态预补偿器作为近似解耦装置，以粗略地减少受控对象的相互作用项。静态矩阵预补偿器由在线估计器调整。此外，将近似解耦系统视为一系列单输入单输出子系统，为每个子系统设计了一个单输入单输出PID控制器。 PID参数是根据PID控制和广义预测控制律之间的关系在线计算的。所提出的方案在仿真示例中进行了数值评估。
In this paper, a new design scheme of multiloop predictive self‐tuning PID controllers is proposed for multivariable systems. The proposed scheme firstly uses a static pre‐compensator as an approximately decoupling device, in order to roughly reduced the interaction terms of the controlled object. The static matrix pre‐compensator is adjusted by an on‐line estimator. Furthermore, by regarding the approximately decoupled system as a series of single‐input single‐output subsystems, a single‐input single‐output PID controller is designed for each subsystem. The PID parameters are calculated on‐line based on the relationship between the PID control and the generalized predictive control laws. The proposed scheme is numerically evaluated on a simulation example.
