Multi-Inputs-Multi-Outputs (MIMO) systems are recognized mainly in industrial applications with both input and state couplings, and uncertainties. The essential principle to deal with such difficulties is to eliminate the input couplings, then estimate the remaining issues in real-time, followed by an elimination process from the input channels. These difficulties are resolved in this research paper, where a decentralized control scheme is suggested using an Improved Active Disturbance Rejection Control (IADRC) configuration. A theoretical analysis using a state-space eigenvalue test followed by numerical simulations on a general uncertain nonlinear highly coupled MIMO system validated the effectiveness of the proposed control scheme in controlling such MIMO systems. Time-domain comparisons with the Conventional Active Disturbance Rejection Control (CADRC)-based decentralizing control scheme are also included.
多输入多输出（MIMO）系统主要应用于具有输入和状态耦合以及不确定性的工业领域。解决此类难题的基本原理是消除输入耦合，然后实时估计剩余问题，接着从输入通道进行消除处理。本研究论文解决了这些难题，提出了一种采用改进型自抗扰控制（IADRC）结构的分散控制方案。通过状态空间特征值测试进行理论分析，并在一般不确定非线性强耦合MIMO系统上进行数值模拟，验证了所提控制方案在控制此类MIMO系统方面的有效性。还包括与基于常规自抗扰控制（CADRC）的分散控制方案的时域比较。
