Abstract

This paper describes the simulations of PID control and PID parameter-scheduling method of an air cylinder system in a spot welding machine. A proper simulation model of the valve controlled air cylinder system is obtained to assess the effectiveness of given control systems. The set-up and set-down responses are analysed in these control systems. Simulation results for various input amplitudes are given to show the effectiveness of the proposed controllers.
