Description
Technical field
The invention belongs to automatic control technology field, in particular, belong to a kind of electric automobile brushless motor control system.
Background technology
Speed regulation control device of motor is for the speed change of electric automobile and direction transformation etc. are arranged, and its effect is the voltage or the electric current that control motor, completes the driving torque of motor and the control of direction of rotation.On early stage electric automobile, the speed governing of DC motor adopts the number of turn of series resistor or change motor field coil to realize.Because its speed governing has level, and the complex structure of additional energy ezpenditure or use motor can be produced, now seldom adopt.Application is thyristor chopping regulating speed more widely, by changing the terminal voltage of motor equably, controlling the electric current of motor, realizing the stepless speed regulation of motor.In the development of electron electric power technology, it also gradually replace by other power transistor chopper speed regulating devices.From the development of technology, along with the application of novel drive motors, the speed regulating control of electric automobile changes the application of DC inversion technology into, will become inevitable trend.
In the rotation direction conversion of drive motor controls, DC motor relies on contactor to change the sense of current in armature or magnetic field, and realize the rotation direction conversion of motor, this makes, and circuit is complicated, reliability reduces.When adopting AC asynchronous motor to drive, the change that motor turns to only need convert the phase sequence of magnetic field three-phase current, and control circuit can be made to simplify.In addition, adopt alternating current motor and Frequency Conversion and Speed Regulation Technique thereof, the Brake energy recovery of electric automobile is controlled convenient, control circuit is simpler.
