Abstract

Under a constant loading condition, use of a controller with constant coefficients can be acceptable for servo pneumatic systems. However, in variable loads with widespread changes, more advanced control methods should be considered to achieve desirable performance. In this paper, an ADAPTIVE CONTROLLER is designed and implemented to a variably loaded servo pneumatic system with PWM driven switching valve. In the experimental setup, a pneumatic circuit is used which consists of one PWM driven fast switching valve instead of an expensive servo or proportional valve. In the designed ADAPTIVE CONTROLLER, real time identification of system parameters is performed using input-output data and controller parameters are adjusted instantaneously. “Self-tuning regulators” algorithm in which the desired closed loop poles and zeroes are predefined, is applied to design the proposed controller. The designed controller is applied to the PNEUMATIC ACTUATOR via an interface board and its results are compared to results of a PD and a multi model controller. Unlike the proposed method which varies the control parameters continuously according to load variations, in multi-model method the control law is selected among a number of fixed controllers. Experimental results demonstrate the high performance of the ADAPTIVE CONTROLLER under variable loads.
