Generalized approach for μ synthesis of robust switching regulators

A general method using /spl mu/ synthesis to design controllers applicable to pulsewidth modulated (PWM) converters is described. System uncertainties from component tolerances are included in the synthesis procedure, adding a quantifiable measure of robustness. Furthermore, these uncertainties have been implemented in a structured format which maximizes available system performance. A boost converter example is presented demonstrating the controller synthesis procedure and advantages of this method.
