Problems solved by technology

Due to the presence or absence of the DC motor used in the environment, the maintenance workload increases and the maximum speed of the application of the asynchronous motor is limited. People have begun to study the structure, which is cheap, simple and reliable, and easy to maintain, but the performance of the speed control technology does not advance the power supply. Electronic components and AC motors, we slow down to improve

Description

technical field [0001] The invention belongs to the technical field of automatic control, more specifically, it belongs to a control system of an AC servo motor. Background technique [0002] The servo system is an automatic control system. The given input quantity of the control system can guide the output controlled quantity of the actuator to change, so the servo system is also called the servo system. It is generally used to make the rotation angle (or displacement) of the controlled object complete a series of prescribed actions according to the requirements of the input command. When the given input of the servo motor changes, the output of the system can automatically, continuously and accurately track the given input. The servo system is generally a closed-loop control system and has a negative feedback function, and the open-loop system can sometimes be used in some specific occasions. The development of the servo system of the motor includes many stages, from the...
