Control of Multivariable Systems Using Modified Local Optimal Controller
نویسندگان
چکیده
In this paper, a modified local optimal control approach is proposed for multivariable systems. As for unknown plant dynamics, system identification must be performed to obtain a model based on which the local optimal controller is designed and implemented. The proposed method guarantee closed loop stability characteristic when dealing with non-minimum phase plant which is a considerable advantage over the original local optimal controller. In addition to computational efficiency and structure simplicity, experimental results on a lab-based test rig confirm the effectiveness and robustness of the proposed local optimal controller over a conventional genetically tuned PID.

This paper concerns a study on the optimal control for nonlinear systems. An appropriate alternative in order to alleviate the nonlinearity of a system is the exact linearization approach. In this fashion, the nonlinear system has been linearized using input-output feedback linearization (IOFL). Then, by utilizing the well developed optimal control theory of linear systems, the compensated ...
