Original Abstract

This paper is dealt with using the adaptive Linear Quadratic (LQ) controller to position control of dish in air flow tunnel. Comparison is done between fixed set PS controller and adaptive LQ controller. Recursive least mean square identification method is used for model computation. LQ controller parameters are computed from this model at each step of computation algorithm. Pole in zero which is placed to about middle of actuator range thanks to dead zone, relatively long sampling period, nonlinearity and dead zone of actuator are the main problems of the dish position control in air flow tunnel.
