A Simple Nonlinear Gain Scheduling Method in Digital PWM Converter ControlIn this paper, we analyze a simple, yet effective nonlinear digital control approach -- gain scheduling of the A/D converter, in PWM converters to achieve system stability and improved dynamic performance. It is shown that a nonlinear gain scheduling could be conveniently realized and implemented, e.g. right after the A/D converter in digital controlled PWM converters. Several simple gain scheduling schemes are analyzed with describing function method, and associated gains are derived and provided. > Download our Digital Control of PWM Converters with Nonlinear Gain Scheduling white paper |
