Description

technical field [0001] The present invention relates to an integrated electrostatic hydraulic servo mechanism, specifically composed of a drive controller, a large motor, a small motor, a variable pump, a piston cylinder, and a valve block. The present invention relates to the technical field of electrostatic hydraulic actuators, specifically In other words, it relates to an integrated electrostatic hydraulic servo mechanism. Background technique [0002] The hydraulic system is widely used in traditional flight control systems due to its advantages of large load, high specific force, and bootstrapping. However, with the development of science and technological innovation, problems such as low efficiency, high failure rate, and high maintenance cost have become increasingly prominent. Since the 21st century, with the development of new materials, motor technology, control science and advanced manufacturing technology, the flight control system has entered the era of power-b...
