Problems solved by technology

Compared with other speed control systems, the SRM drive system has simple structure, reliable operation, high efficiency, and low cost. However, due to the double salient pole structure of the stator and rotor and the high saturation of the magnetic circuit, its flux linkage and torque are both rotor The nonlinear function of position and phase current, the traditional linear control method is difficult to meet the requirements of severe nonlinearity, variable structure and variable parameters of SRM, and it is difficult to obtain ideal dynamic and static performance
And the workload of parameter adjustment is very large, and the control performance of the SRM system is unstable

Embodiment Construction

[0013] As shown in the figure, the present invention includes SRM, power converter, controller, position detector, the controller is the center of the system, it receives the information of speed command, speed feedback signal, current sensor and position sensor sampling signal, and Carry out comprehensive analysis and processing, control signals, and realize effective control of SRM operation status.

[0014] The controller adopts fuzzy immune PSD control.

[0015] Compared with the traditional PID control, the fuzzy immune PID algorithm has a strong self-adaptive ability and improves the system control performance. However, it can also be seen that although fuzzy immune PID control can automatically adjust the proportional gain of the system, the gain of differential and integral is fixed, and it is especially disturbed by nonlinear factors and noise in the process of adjusting control parameters. In addition to the need to adjust the parameter K , η, also need to adj...

The method comprises an SRM, a power converter, a controller and a position detector, and is mainly structurally characterized in that the controller is the center of the system, and the controller receives speed instructions, speed feedback signals, and information of sampling signals of a current sensor and a position sensor and performs integrated analysis processing thereon to control the signals, such that the operation state of the SRM is effectively controlled.

Description

Technical field [0001] The present invention is a fuzzy immune PSD control method that involves a vague immune PSD control method involving a switch magnetic resistance motor speed regulating system. Background technique [0002] The switching magnetic resistance motor (SRM) has received great attention with its superior structure, performance and economic indicators of traditional motors.Compared with other speed regulating systems, the SRM driver system is simple, reliable, high -efficiency, and low cost, but due to the dual convex structure of the rotor and the height of the magnetic circuitNon -linear functions of positions and phase current. Traditional linear control methods are difficult to meet the requirements of serious nonlinear, structure, and variable parameters of SRM, and it is difficult to obtain ideal movement and static performance.And the workload of parameter adjustment is very large, and the control performance of the SRM system is unstable. Invention conten...
