LQR-Based Power Train Control Method Design for Fuel Cell Hybrid Vehicle

الملخص EN

Based on the mathematical model of fuel cell hybrid vehicle (FCHV) proposed in our previous study, a multistate feedback control strategy of the hybrid power train is designed based on the linear quadratic regulator (LQR) algorithm.

A Kalman Filter (KF) observer is introduced to estimate state of charge (SOC) of the battery firstly, and then a linear quadratic regulator is constructed to compute the state feedback gain matrix of the closed-loop control system.

At last, simulation and actual test are utilized to demonstrate this new approach.
