Problems solved by technology

[0004] The BSG system of a hybrid vehicle generally adopts a feedback control method such as PID control. This method has a large dependence on the parameters of the BSG itself. Since the parameters of the BSG itself have serious nonlinearity, strong coupling and time-varying characteristics, the PID control method The actual effect is difficult to achieve the effect of theoretical analysis, and the PID control method cannot simultaneously take into account the optimal effects of system dynamic control, system stabilization, and system disturbance elimination, while the adaptive inverse control strategy can well solve the shortcomings of the PID control method. Therefore, it is necessary to study the adaptive inverse controller of BSG system for HEV

Abstract

The invention relates to a construction method of a hybrid electric vehicle belt driven starter generator controller. The method comprises the following steps of forming a composite controlled object by using an expansion inverter control module, a hybrid electric vehicle BSG, a current detection module and a rotation speed and rotation angle detection and calculation module, establishing a composite controlled object model and a composite controlled object inverse model, enabling the composite controlled object model and the composite controlled object inverse model to be in series connection in a mode that the composite controlled object inverse model is in front of the composite controlled object model, using an output error of the composite controlled object and the composite controlled object model to drive the composite controlled object inverse model, using an output error of the composite controlled object and a reference model to adjust the weight parameter of an inversion controller in an online way, and forming an adaptive inverse controller by using the inversion controller, the composite controlled object model, the composite controlled object inversion model and the reference model. According to the method, the hybrid electric vehicle BSG system disturbance control and system dynamic characteristic control can be separately and independently processed, the two control can reach the best effect at the same time, and the controller has very strong robustness and anti-interference ability.
