摘要

提出了一种双输入双输出耦合油箱系统(CTS)的多目标控制器设计及其实时实现。通过满足极点布置等时域目标和h∞条件等频域目标，实现了多目标控制。该多目标控制采用线性矩阵不等式(LMI)准则，并作为一个凸优化问题进行求解。所计算的多目标控制器增益已在实时dSPACE硬件平台上以实验室规模实现。所得到的控制器提高了闭环系统在参数变化和各种不确定性下的参考跟踪性能，并具有鲁棒性。

Design and realization of a multi-objective controller for a MIMO coupled tank system

This paper presents a design of multi-objective controller for a two input two output interacting Coupled Tank System (CTS) and its real time implementation. The multi-objective control has been achieved by satisfying time domain objective like pole placement and frequency domain objective like H-infinity condition. This multi-objective control has been formulated using Linear Matrix Inequality (LMI) criteria and solved as a convex optimization problem. The multi-objective controller gain thus computed has been implemented in real time dSPACE hardware platform with a laboratory scale process. The resulting controller yields improved performance of the closed loop system for reference tracking with robustness in presence of parameter variation and various uncertainties.
