The article describes a new approach to the issue of controlling hydrostatic systems with fixed displacement pump using the frequency inverter and the simple controller unit. The aim of the article is to present a method of controlling the velocity of scissor lift drive to provide a constant velocity of the platform, regardless of its load, geometry and current location. The main feature of the proposed solution is the use of feedback in the quasi open loop from platform displacement sensor to the velocity control system of the electric motor. To ensure theThere is a possibility of using the proposed control system in a typical hydrostatic scissor lift, with added only an inverter, a platform displacement sensor and a controller to an existing machine. The proposed control strategy has been verified experimentally on an existing drive, and the obtained results show satisfactory mileages and very high accuracy of maintaining and shaping the platform velocity. The developed mathematical and physical models of the whole drive has been verified on the test bench. The conducted research gives information about new possibilities of using the inverter in hydrostatic systems, such as increasing efficiency, decreasing acceleration, decelerations , damping and improve the safety of the operation.
