Abstract:
At present, the study on PIλDμ controller has mainly focused on the analysis of stable domain or the parameter tuning for single index. However, in practical application, various of factors had to be considered for the design of controllers and many performance indexes will be required for the control system. Moreover, there usually exists competition among these indexes. In order to cope with the above problem, this paper utilizes the idea of satisfactory control to design a satisfactory PIλDμ controller with constraints of multiple desired indexes. Moreover, the strategy of solving PIλDμ controller’s parameter is discussed, under the constraint of disturbance attenuation index, sensitivity index and control cost index. The simulation result shows that the proposed method is effective and feasible.
