Problems solved by technology
[0002] With the development of automation technology, various actuators that can receive control information and exert control on the controlled object have been derived. According to the driving energy, they can be roughly divided into: electric actuators, pneumatic actuators, and hydraulic actuators. The advantages also have their own disadvantages. Among them, the advantages of electric actuators are quick response, accurate positioning, and multi-point positioning. Low, disadvantages: poor positioning accuracy, small driving force, generally only two-point positioning can be realized; the advantages of hydraulic actuators are large driving force and good stability, but the disadvantages are bulky and complicated pipelines, generally only two-point positioning can be realized point positioning; at present, there is no actuator that can simultaneously possess: low price, simple system, large driving force, good stability, accurate positioning and multi-point positioning
