| Abstract: | In modern electrical transmission servo system,the test of the rotor position and speed is indispensable,and determines the system performance to a certain extent.Introduced a method to measure motor′s rotate speed with enhanced quadrature encoder pulse(eQEP) module in DSP28335 and photoelectric encoder and put forward an improved method of calculating speed.Error analysis,simulation and experiment prove the feasibility of the proposed algorithm.With the method in this paper,we can design a motor speed solution easily.Ensure speed range and choose the proper parameters of components and program,we can get the motor speed accurately. |
