Abstract: This paper presents the design of the synchronous force controller of a double-axial pneumatic actuating system. This system is ideally decomposed into two independent subsystems, and the coupling effect is considered as the noise effect. So, each subsystem can be simulated as an auto-regressive moving average process with exogenous input (ARMAX) model. Each subsystem can use the self-tuning control (STC) algorithm to design the force controller individually, and then a synchronous force regulator is designed to force one subsystem to trace the other and reach the synchronous force control function. The experiments verify that this approach can be successfully used for the double-axial pneumatic actuating system. In addition, its adaptation and robustness are proven by the frequency response analysis.

Keywords: STC; synchronous force control; double-axial pneumatic system.
