This paper analyzes the linearized dynamic characteristics of an air cylinder system for continuous load positioning control. First, the mathematical model of the cylinder system is derived based on a typical electropneumatic valve whose flow characteristics are dependent on both the applied voltage and pressure. Next, the mathematical model associated with a servovalve whose mass flow rate is proportional to the applied voltage is developed. From the mathematical models, the paper discusses the effects of the valves and the load positions on the air cylinder system dynamics. Some simulation and experimental results are given to illustrate the analysis for the control of different start/stop load positioning.
