Microcontroller (MCU) Based Simplified Optimal Trajectory Control (SOTC) for High-Frequency LLC Resonant Converters
… frequency higher continues. However, the control characteristics of the LLC resonant converter are much more complex than that of the PWM converter due to the dynamics of the resonant tank. This paper employs state-trajectory analysis to describe and analyze the behavior of the resonant …

Long-duration proximity operations flexibly optimized for efficient inspection and servicing using free-orbit dynamics
… problem from the perspective of continuous optimal trajectory control. A numerical optimization framework is presented for developing and analyzing fuel-, energy-, and time-optimal trajectories with multiple phases using Gauss pseudospectral collocation software. Emphasis is placed on energy …

State-plane analysis of resonant converters
… also used to understand and evaluate different control methods of a SRC. The occurrence of large, undesirable tank energy surges with analog-signal-to-discrete-time-interval-converter (ASDTIC) control was investigated and explained using state-plane trajectories. A new control method called …

State-Trajectory Analysis and Control of LLC Resonant Converters
… capability. However, unlike PWM converters, the control of the LLC resonant converter is much more difficult because of the fast dynamic characteristic of the resonant tank. In some highly dynamic processes like the load transient, start-up, over-load protection and burst operation, it is hard to …
