Abstract

The invention relates to one mixture dynamic car motor controller based on DSP, wherein, the integral controller sends operation mode information to control module composed of permanent magnetic motor vector control module, space voltage vector impulse modulation, A / D module and sensor measurement process module, wherein, the motor control module determines its control system structure according to the operation mode and speed order and torque order to realize current, speed, position and its fault testing for motor control.

Description

technical field [0001] The invention belongs to motor control in the field of automatic control, in particular to motor control for hybrid electric vehicles. Background technique [0002] Due to increasingly serious energy problems and environmental problems, people are considering replacing diesel locomotives with hybrid electric vehicles. The electric motor is a key component of a hybrid electric vehicle that combines the advantages of traditional internal combustion engine vehicles and electric vehicles, and its control performance has a decisive influence on the hybrid system. The permanent magnet synchronous motor adopts high-performance permanent magnets, which eliminates the influence of the mechanical transmission chain of the rotary servo motor from rotary motion to linear motion, and has the characteristics of high thrust accuracy, low loss, small electrical time constant, and fast response. Since hybrid electric vehicles are all in the research and development st...
