A Simple Method for Multi-loop Control System Optimization and Design

The standard characteristic polynomial is an effective, simple and intuitional way for the design of multi-loop control systems to reduce the calculation loads. This method in this paper is proposed in order to calculate the initial value of the parameters for control system. The initial value of the multi-loop control parameters are calculated according to the different route parameters, and several types route controller parameters are calculated in off-line processing. NCD (Nonlinear Control Design) optimal method based on standard characteristic polynomial is used to optimize the parameters of the control system. Simulation results show the optimality improvement by the method. Furthermore , robustness of control system designed is better.
