Abstract. The actual conditions of the full range suspended pneumatic system can reflect the characteristics of the measured parts more truly. According to the actual working conditions of the pneumatic lifting device which is based on the Kingview configuration software mainly about suspension performance test, response test and stroke test, to test the actual performance of pneumatic lifting system and the performance requirements of test design, then ensure it in an actual work with safety and stability.

The design of the controller of the pneumatic hoist system is the most important step in the whole work process. The quality of the design of the controller is directly related to the realization of the system. This paper elaborates the detailed design of the system in a few steps. Firstly, a set of optimal control parameters kp *, ki * , and kd * are selected. Then the fuzzy self-tuning PID controller is designed for the valve-controlled cylinder system. Finally, the response characteristic simulation of the fuzzy self-tuning PID controller is designed based on Matlab/Simulink platform. From the result and analysis, it can be seen from the simulation results that through the adjustment of the fuzzy self-tuning PID controller, the system adjustment time ts are within 0.8s, and the steady-state error rate is controlled within 3%.
