Problems solved by technology

The shortcomings of this kind of controller are also obvious. There are multiple PI controllers in the entire control system, and at least six controller parameters need to be tuned, which will bring a lot of workload in practical applications; defects, the dynamic characteristics of the system will be limited

Abstract

The invention discloses a hybrid electric vehicle-used BSG AC motor anti-interference composite controller construction method. A rotation speed and load torque are used as input of a load compensation controller, and voltage ud1 and uq1 is used as output; an optimal controller gain matrix, a reference rotation speed, reference current, a rotation speed and current id and iq are used as input of astate feedback controller, and voltage ud2 and uq2 is used as output; a rotation speed and current iq are used as input of a voltage decoupling controller, and voltage ud3 and uq3 is used as output;the optimal controller gain matrix is acquired by adopting a controller parameter optimization module; and voltage ud1, uq1, ud2, uq2, ud3, and uq3 is combined as first-part input of a voltage-limiting controller, the global optimal parameters of the state feedback controller are acquired through a flower pollination algorithm, and on the premise of ensuring safety operation of the motor, the maximum voltage supplied to the motor can be effectively improved, and the saturation phenomenon of the controller is suppressed.

Description

Technical field [0001] The present invention belongs to the field of intelligent vehicle control, and a power transmission control device technology, particularly to a driving belt using the integrated starter / generator unit (Belt-driven Starter Generator, referred to as BSG) constructor AC motor controller. Background technique [0002] Of electric vehicles is a key way to achieve energy saving and reduction of automotive, belt driven starter best use of hybrid technology weak / machine generator (BSG) is considered to be efficient vehicles at this stage to achieve energy saving of automobiles one. BSG is a particularly optimized hybrid system for instant start condition from idling and the drive of an automobile engine. The system can be implemented in a conventional automobile, such as urban jam complex conditions, shut down the engine at idle while waiting for traffic lights, quickly led to the engine idling condition and the vehicle start car energy recovered during brakin...
