This book mainly emphasizes on novel optimization techniques namely 'Circular Method of Optimization' and 'Spherical Method of Optimization'. The author has programmed these techniques in MATLAB 7.7. Circular Method of Optimization mainly concerns with the constraint optimization problem with two independent variables and Spherical Method of Optimization mainly concerns with three independent variable problems. These techniques were implemented on Class A chopper and then the results were implemented on actual hardware of the same circuit. Finally the software and hardware results were...
