Modeling and Control of Proportional Valve with Synchronous Motor
The paper describes the research results of modeling and control of proportional valve with synchronous motor type PMSM (Permanent Magnets Synchronous Motor). In the paper, a simulation model of the proposed valve was developed and described. The model included the square root flow characteristics, nonlinearity of the hydraulic actuator, valve dead zone and saturation of the flow. The study included the investigations of the basic characteristics, such as valve flow characteristic and step responses. In order to determine the basic parameters of the valve, the test stand was built, on which the new valve and the servo drive with this valve were tested. A servo drive control system was based on PLC with touch panel and inverter module. In the paper, the chosen investigations results of the valve and the servo drive system are presented and shortly discussed.
