Abstract：This paper compares the expressions and settings of two kinds of proportional integral (PI) regulators based on real and complex coefficients, respectively, and analyzes the principle of the latter in detail. The advantages and disadvantages of the two kinds of PI regulators are then compared, such as the decoupling properties of control structure, the dynamic response characteristics of the current loop, and the parameter robustness and so on. Simulation and experimental results are carried out to validate the theoretical analysis.
