Abstract
The utility model discloses a kind of Electric Bicycle Driver, comprise PI controller, neuron structure changes PI controller and the PWM controller of connecting successively, described PI controller input end connects storage battery, and described PWM controller mouth connects power driver module; Also comprise the current feedback and commutation position transduser that are connected to brshless DC motor, the mouth of described current feedback is connected to neuron structure changes PI controller input end and forms closed-loop current control link, described commutation position transduser mouth is connected to PWM controller input end and forms position-force control link, and described commutation position transduser mouth also forms speed closed loop controlling unit by rotating speed conversion model calling in PI controller input end.Adopt electric current, rotating speed, position Three-loop control, degree of cyclic irregularity can be made little, faster system response and steadily, speed overshoot is little, has both improved the comfort level of riding during speed change, has extended again the service life of motor.
Description
Technical field
The utility model relates to Electrical Bicycle field, is specifically related to a kind of Electric Bicycle Driver.
Background technology
Along with the expansion of city extension, the demand of Motorization constantly increases, the vehicle whether convenient left and right the activity space of people.The self-propelled vehicle such as automobile, motor bike consumes petroleum, the tail gas of discharge causes very large pollution with the living environment of noise to us sent, affect the healthy of the mankind, along with environment and energy problem are more and more subject to people's attention, bicycle returns to the life of people, but traditional manpower self vehicle speed is slow, foot-operated comparatively sweat of riding also, can not adapt to the fast pace of modern's life and the needs of trip; Electrical Bicycle has the environmental protection feature of zero-emission, low noise, has become very popular Personal Transporter at present.
The motor that Electrical Bicycle adopts mainly divides brushless motor and brshless DC motor two kinds, brushless motor is had to adopt mechanical commutation, life-span is short, noise is large, efficiency is low, more fragile, brshless DC motor adopts electronic commutation, fundamentally eliminate wear of brush and gear wear, noise is little, the life-span is long, efficiency is high, reliable, maintenance is simple; The controller of current employing brshless DC motor Electrical Bicycle generally adopts electric current, rotating speed double-closed-loop control, and torque fluctuation during motor commutation is large, and speed of response is slow, the service life of ride comfort level and motor when affecting speed change.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of Electric Bicycle Driver, the Electric Bicycle Driver that can solve existing employing brshless DC motor generally adopts electric current, rotating speed double-closed-loop control, cause torque fluctuation during motor commutation large, speed of response is slow, affects the problem in the service life of comfort level and the motor of riding.
The utility model is achieved through the following technical solutions:
A kind of Electric Bicycle Driver, input end connects storage battery, mouth connects the power driver module of electric bicycle brushless direct current motor, comprise PI controller, neuron structure changes PI controller and the PWM controller of connecting successively, described PI controller input end connects storage battery, and described PWM controller mouth connects power driver module; Also comprise the current feedback and commutation position transduser that are connected to brshless DC motor, the mouth of described current feedback is connected to neuron structure changes PI controller input end and forms closed-loop current control link, described commutation position transduser mouth is connected to PWM controller input end and forms position-force control link, and described commutation position transduser mouth also forms speed closed loop controlling unit by rotating speed conversion model calling in PI controller input end.
Described current feedback is the sampling resistor be connected in the DC bus of brshless DC motor.
Described commutation position transduser is the Hall element of brshless DC motor.
Described rotating speed conversion module is s-f metering circuit.
The utility model advantage is compared with prior art:
One, adopt electric current, rotating speed, position Three-loop control, degree of cyclic irregularity can be made little, faster system response and steadily, speed overshoot is little, has both improved the comfort level of riding during speed change, has extended again the service life of motor;
Two, adopt neuron structure changes PI controller, overcome the shortcomings such as intrinsic the existing of common PI controller overshoot, speed of response are slow, poor robustness, more adapt to the requirement of the fast closed-loop current control link of dynamic change.
Accompanying drawing explanation
Fig. 1 is controller architecture block diagram of the present utility model.
Detailed description of the invention
A kind of Electric Bicycle Driver as shown in Figure 1, comprises PI controller, neuron structure changes PI controller and the PWM controller of connecting successively, and described PI controller input end connects storage battery, and described PWM controller mouth connects power driver module, also comprise the current feedback and commutation position transduser that are connected to brshless DC motor, described current feedback is the sampling resistor be connected in the DC bus of brshless DC motor, commutation position transduser is the Hall element of brshless DC motor, the mouth of described sampling resistor is connected to neuron structure changes PI controller input end and forms closed-loop current control link, described hall sensor output is connected to PWM controller input end and forms position-force control link, described hall sensor output is also connected to PI controller input end by s-f metering circuit and forms speed closed loop controlling unit.
