Prediction control method for output power of proton exchange membrane fuel cell

The invention discloses a prediction control method for output power of a proton exchange membrane fuel cell. Firstly a fractional order state space model of the proton exchange membrane fuel cell isdiscretized by adopting a short-term memory method; secondly a control variable, a controlled variable, a control step size and a predicted step size are selected; thirdly a constrained prediction control problem is converted into a constrained optimization problem, and Hildreth quadratic programming constraint is performed on the optimal control rate of the control variable; and finally MPC control is performed on the output power based on the optimal control rate of quadratic programming. According to the method, the operation time of a control system can be obviously shortened; compared with traditional PID control, the output power of the proton exchange membrane fuel cell under a control strategy has good dynamic response characteristics; the control variable is always changed withina constraint range; and a
