Description

A kind of multi-level redundant mutual inspection motor controller and control method technical field The present invention relates to the technical field of motor control, specifically a kind of multi-level redundant mutual inspection motor controller and control method. Background technique With the development of power electronic technology, motor controller has become an important part of modern motion control. Controllers are widely used in the field of injection molding machines, textile machinery, packaging machinery, CNC machine tools, aerospace and so on. motor The controller is the main source of power for various moving objects. Its performance, characteristics, and reliability determine the performance of the entire motion system. Whether the performance is good or bad, the traditional motor controller is generally a processing chip to control a motor, or a processing chip Add an auxiliary chip to control one or more motors, but when controlling the mo...

Problems solved by technology

The motor controller is the main source of power for various moving objects. Its performance, characteristics, and reliability determine the performance of the entire motion system. Traditional motor controllers generally use a processing chip to control a motor, or a The processing chip plus an auxiliary chip controls one or more motors, but when controlling the motor, at the same time, the traditional motor controller does not have chip-level correction and mutual inspection, and at the same time, the control method is single, the control mode is single, the reliability is poor, and it is only applicable to specific It is not suitable for all kinds of motors, and many controllers cannot control multiple motors at the same time, and the PWM output of the motor control signal is only solved by the algorithm of the processor, without further comparison and adjustment

These defects often cause the motor controller to be dedicated every time, which increases the cost of research and development. At the same time, the reliability of the motor controller is reduced, the applicability is reduced, and there is no redundancy. Once a problem occurs, the entire system will crash.
