DELTA MODIFICATION OF SELF-TUNING CONTROLLERS
Original language description
This contribution presents the application of self-tuning digital PID controllers for process control modelled by -models. The process is identified by the regression (ARX) model using the recursive least squares method (RLSM) with LD decomposition and applied directional forgetting. The basic RLSM algorithm has been modified for the -model structures. Controller synthesis is designed by using method where the required transfer process behaviour of a closed control loop can be achieved by selecting ourown circular frequency and relative damping in the characteristic equation for connected second-order plants. Two digital PID controller structures have been designed in -modification. Controller output in the -model has excellent behaviour (without oscillation), the -parameter estimates have excellent convergence and over a short sampling period converge to their continuous versions.
