A nonlinear control algorithm for fuel optimal attitude control using reaction jets
… controller. The benchmark controller is a basic pulse-width modulator (PWM) with a proportional derivative controller driving the feedback loop. The second is a standard rate-ledge controller (RLC) with full-on or full-off pulse commands, while the third varies the duration of the RLC pulse …

Time-based control techniques for integrated DC-DC conversion
… sum time signals. A simple flip-flop generates a pulse-width modulated signal from the time-based output of the controller. Hence time-based control eliminates the need for a wide bandwidth error amplifier, pulse width modulator (PWM) in analog controllers or high-resolution analog-to-digital …

High-Frequency Modeling and Analyses for Buck and Multiphase Buck Converters
… save the output capacitors, the control-loop bandwidth must be increased. However, the bandwidth is limited in the practical design. The influence from the switching frequency on the control-loop bandwidth has not been identified, and the influence from multiphase is not clear, either. Since the …
