Sažetak
Design and application of the accurate position control for a pneumatic cylinder based on the sliding mode technique is presented. The controller is implemented on a TMS320LF2407 DSP based controller board. The advantage of the proposed algorithm for position control is the accuracy better than 10 µ m, approved through the wide range of dynamic and static load (disturbance) variation in the entire operation area. The paper describes the nonlinear model of the pneumatic cylinder and the three main design steps of the proposed control method ; sliding surface design, control law selection and chattering free implementation. The large number of experimental tests on the servopneumatic system with proposed sliding mode algorithm confirmed high accuracy and robustness in the horizontal and vertical position control.
