Description
technical field [0001] The invention belongs to the technical field of direct-drive electro-hydraulic servo valves, in particular to a controller for direct-drive electro-hydraulic servo valves with multi-parameter requirements. Background technique [0002] The electro-hydraulic servo valve is a key component in the electro-hydraulic servo control system. In recent years, with the rapid development of construction machinery and the widening of the application field of the electro-hydraulic servo system, higher technical requirements have been put forward for the electro-hydraulic servo valve, such as high pressure , large flow, anti-interference, anti-pollution, high frequency response, etc. The traditional nozzle baffle type electro-hydraulic servo valve has been difficult to meet these requirements, so there is an urgent need for a new type of electro-hydraulic servo valve, which cancels the nozzle baffle group, replaces the torque motor with a linear force motor, and imp...
