A GENERALIZED SELF-TUNING CONTROLLER AND ITS APPLICATION TO FLIGHT ALTITUDE CONTROL

This paper presents a generalized self-tuning controller with on-line choice of weighting terms combined with generalized minimum variance control and pole-placement strategy.This controller adopts least square algorithmto estimate its parameters and it is implemented in indirect scheme.It is also globally convergent.Simulation re-search about the application of the controller to flight altitude control is aIso made.Its results show that the con-troller can adapt changes of the system parameter due to flight condition variation to obtain a satisfactory controlperformance.
