A Multivariable Implicit Pole Assignment Self-Tuning controller and its Applications

In this paper, a pole assiqnment self-tuning controller is presented. It not only can control unstable and/or nonminimum phase systems but also the multivariable system with arbitrary unknown and/or varying time delay structure. It is implemented by the implicit scheme, i.e., the input output data can be used to directly identify the controller parameters. It avoids the solving of matrix equations on line and improves the robustness of the algorithm proposed. The results of simulation and control for a multivariable electrically heated system in real time show that this controller has good performances.
