| Abstract: This paper introduces a new tuning technique for digital PID controller parameters of multivariable systems. This technique is based on the modified Local Optimal Controller (LOC) parameters for certain predefined model structures. The modified LOC parameters can be obtained using the identified parameters of the predefined model structure. As such, the digital PID controller parameters can be tuned using the model parameters of certain predefined structures and a single tunable parameter related to the LOC for each output of the multivariable system. Becoming a model-based controller, the PID controller parameters can be adjusted in automatic mode. This new technique is compared with the existing Genetic Algorithm (GA) technique for tuning digital PID controller parameters. The comparison is based on the experimental results of the Bytronic Process Control Unit (PCU). | ||||
