Due to pneumo-mechanical power conversion process nonlinearities and process parameters (volumes and initial pressures of pneumatical cylinder working chambers) on line change it is problematic to ensure satisfactory control quality of pneumatic proportional servo drive. Considering that all nonlinearities are concentrated in the force generation stage, application of adaptive force control mode is suggested. Electropneumatic servo drive with reference model based signal adaptive force controller is developed and investigated in this paper. It is presented the strategies of reference model choice and are given control quality investigation results of electropneumatic servo system
