Motor controller of layering multinuclear structure and control method thereof

Abstract

The invention relates to a motor controller of a layering multinuclear structure and a control method thereof. The motor controller comprises a power contravariant unit driving a motor to operate, an application interface function module, a motor control function module and a driving function protection module, the application interface function module sends state information of the controller to an external control system, receives control signals and sends control commands to the motor control function module; the motor control function module receives the control commands, detects states of the motor, completes control operation and sends control pulses to the driving function protection module; the driving function protection module receives the control pulses, processes the control pulses and sends the control pulses to the power contravariant unit; and the driving function protection module detects operating states of an inverter and controls the power contravariant unit. The motor controller is divided into three layers of independent systems from inside to outside and from bottom to top, the three layers of independent systems increase a driving layer system, a control layer system and an application layer system, all modules are tightly connected, functions are relatively independent, system breakdown is avoided under extreme cases, reliability is high, and safety is strong.

Description

Technical field: [0001] The invention relates to a motor controller and a control method thereof. Background technique: [0002] With the aggravation of the global energy crisis, energy conservation and emission reduction, and getting rid of dependence on oil have become global scientific and technological hotspots, and have also become a country's strategic needs. As a result, new energy vehicle technology, which is different from traditional fuel vehicles, has made great progress and has begun to be applied globally. [0003] Most new energy vehicles use electric motors as power. Whether the entire power system operates reliably and whether the control is excellent depends on the motor controller. A complete new energy vehicle motor controller needs to complete the following functions: [0004] ●Motor state detection and control; [0005] ●Inverter drive signal setting and its fault detection and protection; [0006] ●Receive the given running control command from the...

AI Technical Summary

Problems solved by technology

[0008] As can be seen above, the functions of the motor controller are quite complex, and because the motor runs at a high speed and the operating conditions are complex and changeable in new energy vehicles, the real-time requirements for motor control are high. If there is a loophole in a certain function, it will It will cause the system to crash, ranging from the motor not responding to the control, to the severe case of out-of-control "flying car"
