A method for controlling a rectifier includes determining reactive power and active power according to sampled voltages and sampled currents of a three-phase alternating current signal, determining given active power according to a given voltage and a sampled voltage of a direct current signal, determining a target voltage vector for model predictive control according to the active power, the reactive power, the given active power, and a damping-injected Hamiltonian dissipative model, performing the model predictive control according to the target voltage vector to obtain a control signal for the rectifier, and controlling the rectifier according to the control signal.
