Neural network applications in the control of power electronic converters

Attempts have recently been made to apply Neural Networks to control systems where they are to deal with any modeling uncertainties that may exist. This thesis proposes the Neural Network controller as a viable alternative to the conventional and widely used PI regulator for the regulation of Power...
