description The invention discloses a novel energy feedback type suspension control system based on a PI feedforward model predictive control algorithm, and belongs to the field of vehicle control, and the system comprises the steps: S1, building a kinetic model of an energy feedback suspension system; s2, establishing an energy feedback control system simulation model; s3, designing a voltage outer loop controller, and calculating to obtain a reference current through a PI controller and a model-based feedforward compensator; meanwhile, designing a load disturbance observer to observe the change of the load; s4, designing a current inner loop controller, and calculating through a model prediction control algorithm to obtain an optimal duty ratio; meanwhile, an inductive current observer is designed to carry out equivalent estimation on inductive current so as to avoid the influence of the change of input voltage and inductive resistance on the quality of feedback electric energy. According to the invention, the quality
