“…PMSM are becoming popular in the new energy industry on account of its simple operation, high efficiency, and low loss [1] . There are two commonly used control methods of PMSM [2] , one is direct torque control, and the other is vector control. Torque control has the disadvantages such as torque and flux ripple, vector control with system parameters, shortcomings, and so on [3] , all-digital fuzzy control system is a strong coupling, multi-variable and non-linear system, and the process of running vulnerability to motor parameter variations and load disturbance uncertainty interference factors.…”

Times are changing with each passing day, and permanent magnet synchronous motors are becoming popular in the new energy industry on account of its power consumption conversion rate is the same, its pollution is relatively small. For the problems of Buffeting and error when the system reaches stability vector control of PMSM, paper researches and tenders a kind of vector control based on a double power sliding mode permanent magnet motor. First, the traditional PI controller is replaced by a modified convergence-law sliding mode control in the current loop to improve overshoot and sliding mode jitter, new system stability is determined using Lyapunov function. Finally, simulation system in MATLAB/simulink is built, and the double-power sliding mode approach law, common sliding mode approach law, and PI control are compared and verified, and the waveforms of the three methods are compared. Paper, method of double power reaching law is used to track and control the current loop, the innovation point is that the double exponential law of approach, its advantage in (1) compared with other general convergence speed law of approach of sliding mode control(SMC) for faster relative to the general SMC (2) the steady-state error is smaller, effectively prevent the chattering.

<p>Electrical machines with eccentrically positioned rotors experience strong unbalanced magnetic pull directed towards the narrowest air gap. This unbalanced force increases the rotor eccentricity and degrades machine performance. Accurate computation and reduction of electromagnetic force are required for controlling electromagnetic vibration, and this can be achieved by employing a bridge-configured winding scheme. This paper presents a two-dimensional bridge configured permanent magnet synchronous machine model to investigates the force compensating strategy under different eccentricity of PMSM. Furthermore, the force components under rotor eccentricity are compared with Bridge ON and Bridge OFF conditions. The connection of bridge points allows the different currents to flow in different coil groups, reducing the unbalanced magnetic pull. The modelling and simulation of PMSM have been done using time-stepping finite element method. The finding indicates that connecting the bridge points can significantly reduce the amplitude of the electromagnetic force components induced by different rotor eccentricities.</p>
