Abstract

The invention discloses a PI (Proportional Integral) control method for exciting currents of a single-phase induction motor and belongs to the single-phase induction motor control field. A utilization system of the control method is formed by a controller, a power driving unit, a single-phase motor and a current detection sensor and the controller is formed by a comparator, a proportioner, an integrator and a summator. The PI control method for the exciting currents of the single-phase induction motor comprises firstly identifying an excitation parameter A of the single-phase induction motor and then adjusting a proportional control parameter Kp and an integral control parameter Ki of the controller. According to the PI control method for the exciting currents of the single-phase induction motor, parameters of the PI controller are regulated according to parameters of the single-phase induction motor during debugging, so that the PI controller can be adjusted purposely, parameter adjustment blindness of the PI controller is restrain, time and energy are saved, and a good current control effect is obtained.

Description

technical field

[0001] The invention relates to a single-phase induction motor excitation current system, in particular to a control method for a single-phase induction motor current control system, which belongs to the field of single-phase induction motor control. Background technique

[0002] Single-phase induction motor current control must adopt closed-loop control to obtain excellent current control performance. The single-phase induction motor excitation current closed-loop control system includes a controller and a controlled object. How to adjust the single-phase induction motor current control system according to different controlled objects and PI (proportional integral) controller parameters is a problem to be solved in the prior art. At present, in the known prior art, the proportional control parameters and integral control parameters of the PI controller are directly adjusted by trial and error method or empirical method, instead of adjusting according to the...
