Real-Time Pressure Monitoring and Control of a Hydraulic System without Sensor

摘要

In a traditional hydraulic system, a pressure sensor is used to implement feedback control. However, there are many industrial cases where applications have required a pressure feedback but the media is so corrosive and/or dangerous, the sensor becomes prohibitively expensive. This research proposes the control of a pumping system which can achieve the desired pressure without a pressure sensor. Along with the control system itself, a user friendly interface is developed to operate over the Ethernet.
