ADAPTIVE CONTROL FOR ELECTRO-PNEUMATIC SERVO CONTROL SYSTEM

An electro-pneumatic proportional/servo control system(EPSCS)with adaptive control scheme isdiscussed.By systematical study of the plant or controlled object of the EPSCS,one can find that theinertial load,force load,supply-pressure and other factors will influence the mathematical model of theplant.An adaptive control strategy is thus employed.With Model Reference Adaptive Control(MRAC),the EPSCS is discussed.Furthermore,a method of robust adaptive control is introduced into EPSCS and the results show that the adaptability of the EPSCS is improved significantly by means of the controlschemes.Some experimental results and conclusions are given.
