DESIGN OF PID CONTROLLERS FOR DELAYED MIMO PLANTS USING MOMENTS BASED APPROACH

Abdelmadjid Bentayeb - Nezha Maamri - Jean-Claude Trigeassou

   This paper deals with the design and the optimization of robust PID controllers for delayed Multi-Inputs Multi-Outputs (MIMO) plants using moments approach. This methodology is based on a reference model used to specify both time and frequency closed loop requirements. The PID controller is obtained after a Non Linear Optimization procedure minimizing a quadratic cost between the reference model frequency moments and the closed loop ones.

Keywords: PID control, reference model, moments, delay
