Abstract
As for the three-phase inverter,this paper introduces a space vector pulse width modulation( SVPWM) based on PID neural network. A three-phase has the switch state of vector and the implementation of its modulation al-gorithm is very complex. This research adopts PID neural network modularization design for rapid implementation of SVPWM algorithm instead of the traditional neural network. The three-layer feed forward PID neural network,pro-duces three-phase symmetrical 12 sinusoidal pulse width modulation waveforms with the instruction voltage and angle as the input information and with the aid of a simple timer and logic circuit. The measured data are used to test the proposed system by a back propagation algorithm in the MATLAB Neural Network Toolbox. Experimental results show that the method is feasible,and can effectively improve response speed and stability in all linear regions.关键词
