Abstract

The invention belongs to the technical field of power control, and particularly discloses a power control optimization method based on a closed-loop control algorithm, and the method comprises the following steps: S1, obtaining an open-loop Bode diagram through a scanning system of a frequency response analyzer; S2, adjusting and compensating network parameters through MATLAB to reach a system steady state; S3, converting the transfer function from the s domain to the z domain through Laplace transformation; S4, discretizing and transposing into a fixed-point difference equation; and S5, converting the parameters into fixed-point parameters and putting the fixed-point parameters into S32K to carry out difference equation calculation. According to the method, the problem that the operation speed of the S32K is lower than that of other special control chips is solved, the response speed is greatly improved while the accuracy is guaranteed, power control can be carried out by achieving a closed-loop control algorithm on the S32K, meanwhile, the basic requirements of CAN communication, sampling and the like are met, and the method can meet the functions of constant-voltage and constant-current control, ripple suppression and the like.
