Construction method of BSG self-adaptive fault-tolerant controller for hybrid electric vehicle

The invention discloses a construction method of a BSG self-adaptive fault-tolerant controller for a hybrid electric vehicle. The method includes: constructing a composite control object; constructing a normal least squares support vector machine inverse model of the composite control object, and constructing a least squares support vector machine inverse model database; selecting the least squares support vector machine inverse model of the composite control object, and serially connecting the least squares support vector machine inverse model database in front of the composite control object to form a pseudo linear system; and performing fault-tolerant control to the composite control object. By the method, time-varying complex non-linear control of the strong coupling BSG for the hybrid electric vehicle is converted into simple linear control, and fault-tolerant control of the BSG is achieved. High-performance control of the BSG system for the hybrid electric vehicle is achieved by designing the self-adaptive closed-loop controller.
