Abstract

This paper deals with the design and application of the Exact-Linearization Control method to a 3/3 pneumatic proportional pressure control valve. Based on the nonlinear dynamic model of the valve, a control law will be derived which guarantees a specified closed loop response. The chosen approach is characterized by adaptive properties because the connected volume is regarded in the control algorithm. The response of the valve to setpoint changes under different working conditions and its disturbance behaviour are presented by some experimental results, which are clearly illustrating the effectiveness of the proposed control strategy.
