Description

technical field [0001] The invention belongs to the technical field of motor control, and in particular relates to a permanent magnet synchronous motor control system, method, controller and application thereof. Background technique [0002] At present, the closest existing technology: traditional DSP-based motor development is divided into four stages: requirement definition, design program algorithm, hardware implementation and verification test. In the algorithm design process, the system is often simulated in MATLAB / Simulink first, and then the program code is designed in the DSP development environment CCS, and finally the execution results are compared with the simulation results to fine-tune the program. In this process, the next stage must be started after the previous stage is over, so that the entire development process cannot be organically combined, which causes various problems and seriously affects the development efficiency of the project. Moreover, the contr...

Problems solved by technology

In this process, the next stage must be started after the previous stage is over, so that the entire development process cannot be organically combined, which causes various problems and seriously affects the development efficiency of the project.

Moreover, the control circuit of each motor is different from the microprocessor, which leads to the need to reconfigure the registers every time the target motor is changed.

It is difficult to distinguish whether the motor parameters or the algorithm is not suitable when the control effect is not ideal

[0003] To sum up, the problems existing in the existing technology are: the traditional motor control mode has low efficiency, poor security, and poor code portability

[0004] Difficulty in solving the above technical problems: When the control algorithm for a certain target motor needs to be transplanted to other microprocessors, different processors and different control targets need to be readjusted and tested. Moreover, engineers who are particularly familiar with the target and algorithm configuration are required to operate, which is time-consuming and laborious
