Control of Higher Order System Using Delta Models

This contribution demonstrates possibility of delta models for identification and process control of higher order plants by the help of self-tuning delta controllers. Simulation will show behaviour of second order delta controllers used for control of higher order plants. It is used pole placement method and method Ziegler-Nichols for syntheses of controller, comparison is done for different structures of control loop. System is identified by recursive delta identification – plant is approximated by the second order system. Contribution presents control ability of higher order systems by the help of second order delta controller.
