the deadtime pensation algorithm according to the pensation rules table TABLE I. III. EXPERIMENTS In order to test and verify the proposed deadtime pensation method of SVPWM, experiments are established and made. The experiment system consists of PMSM, threephase voltage source inverter, control platform, dynamometer, heat dissipation system, et type of IGBT in the inverter is CM600DY24A produced by Mitsubishi. The control platform is based on DSP TMS320F2812 produced by Texas is a special motor control DSP which has many advantages and can implement highperformance motor control such as FOC (Field Oriented Control) and DTC (Direct Torque Control). The main parameters of the control objectPMSM used in experiments are listed in TABLE II. For different pulse width pensation values of , and , the deadtime pensation experiments are all made. shows the experiment waveforms of threephase stator currents and the sector number of stator current vector for different pulse width pensation values, and shows the corresponding frequency spectrums. TABLE II MAIN PARAMETERS OF PMSM USED IN EXPERIMENTS (a) No Compensation (b) Pulse Width Compensation Value = (c) Pulse Width Compensation Value = (d) Pulse Width Compensation Value = (e) Pulse Width Compensation Value = . Experiment Waveforms of Threephase Stator Currents Here, the CPU frequency of DSP is set at 150MHz,the switching frequency of IGBTs in threephase voltage inverter is set at 10kHz, the deadtime is set at through the hardware and software of DSP,the motor control method adopts FOC algorithm, the dc link voltage is set at about 330V,and the phase current is controlled at about 10 A. (a) No Compensation (b) Pulse Width Compensation Value = (c) Pulse Width Compensation Value = (d) Pulse Width Compensation Value = (e) Pulse Width Compensation Value = . Frequency Spectrum of Stator Current (Phase A) It can be seen from and that, pared with experiment results of no pensation, through the proposed deadtime pensation algorithm the threephase stator current waveforms of PMSM are all improved effectively and the harmonic ponents of threephase stator currents are also decreased effectively. Especially when the pulse width pensation value is set at about ,pared with experiment results at the other pulse width pensation values of , and , the pensation result is the best and the harmonic ponents of threephase stator currents are the least. Therefore, the proposed deadtime pensation method is correct and feasible. IV. CONCLUSIONS The proposed deadtime pensation method can be implemented easily through software algorithm without any extra hardware design. So long as the c urrent vector angle φ is determined by the α and βaxis ponents of stator current vector in the twophase static reference frame, the deadtime pensation algorithm can be carried out effectively according to the corresponding deadtime pensation rules table. Finally experiments are established and made on the PMSM driving platform based on DSP TMS320F2812 and the results indicate that the proposed method can improve the current distortion and decrease the torque pulsation effectively, especially when the pulse width pensation value is equal to about ,the proposed method is correct and feasible.
