Abstract:
Phase profile generator systems and methods are disclosed. A system includes a signal generator, a target phase trajectory module, an error detector and a control loop filter. The signal generator is configured to generate an output signal. In addition, the target phase trajectory module is configured to track a target phase trajectory and determine a next adjustment of the output signal to conform the output signal to a portion of the target phase trajectory. Further, the error detector is configured to determine an error between the output signal and a current target phase trajectory value that precedes the portion of the target phase trajectory, where the determination of the error is independent of the next adjustment of the output signal. Moreover, the control loop filter is configured to control the signal generator in accordance with both the next adjustment and the error to generate a phase profile.
