The Research On The Noise Of Switched Reluctance Motor System By Simulation Based On Matlab

Switched Reluctance Motor is a new pattern of timing electricity that rises at the time of eighty of twenty century, which is being developed quickly. It not only keeps the advantage of AC machine which has the virtues of simple structure, firmness and dependable, and the advantage of DC which has the virtues of favorable controlling, but also has the advantage of cheapness, high efficiency and high ability of applying which is hardly achieved by AC and DC system. It is a strong competitor of modern drive system, and it has wide foreground of development. But because of the noise when stator librating, which is produced by radial suction at the time of running, its application is restricted, and SRM engine per se is a non-linearity system which has the spy of many controllable measures and strong coupling. In order to find the better capability of timing, we use the method of computer emulating to get the better way of SRM controlling.In this paper, the main work is as follow:1,The math model of SRM is improved, and gives the modeling of SRM;2,The in-out pressure,current, load pressure,current,inductance are tested by emulating, using S-function emulating module in MATLAB/Simulink;3,Under control of Angle Position Control, The chop force and radial force for SRM are accounted by emulating at the different control of dredge angle and barrier angle, and the chop force and radial force are also compared.The result indicates that advisably minimizing dredge angle and barrier angle Under control of Angle Position Control for SRM is a main means to adjust the wave of radial force and peak value, which can effectively reduce radial force, restrain librating, so as to achieve the aim of reduce noise.
