The invention discloses a heat pump system based on robust model prediction and a control method thereof.The heat pump system comprises a heat pump cabin heating loop and a heat pump cabin refrigerating loop, and a nominal system control law and an additional feedback control law are superposed to serve as a control signal of the heat pump system; controlling the rotating speed of the compressor, the opening of the first electronic expansion valve, the opening of the second electronic expansion valve and the air volume of the fan; the nominal system control law is obtained by constructing a nominal system space state prediction model in a nominal system model prediction controller, establishing a heat pump system performance index function, and solving state quantity constraints and control quantity constraints; the additional feedback controller inputs the actual system state quantity at the moment k and the nominal system state quantity at the moment k + 1, the additional feedback controller is made to be stable at the equilibrium point through the Lyapunov function, and then the additional feedback control law is solved. The heat management of the electric vehicle is more effective and energy-saving.
