Description

technical field [0001] The invention relates to the technical field of motor control, in particular to a multi-level redundant mutual detection motor controller and a control method. Background technique [0002] With the development of power electronics technology, motor controllers have become an important part of modern motion control. Motor controllers are widely used in the fields of injection molding machines, textile machinery, packaging machinery, CNC machine tools, and aerospace fields. 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 a...

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.
