Abstract:
1. A high-speed precision servomechanism control system, comprising: a closed-loop control servomechanism implemented with feedback control and feedforward compensation to control output states of a physical plant in response to a command input stream applied to the control system; and a corrective input generator responsive to the command input stream to provide a refined input stream to which the physical plant responds to achieve within an operational tolerance a desired output state corresponding to the command input stream, the corrective input generator implemented with correction input mapping that provides for an arbitrary command input stream a match solution causing the physical plant to achieve the desired output state corresponding to the arbitrary command input stream, the corrective input generator comprising a FIR filter having an output and implemented with filter coefficients computed to provide the match solution, and the corrective input generator implemented with an input delay to the arbitrary command input stream combined with the output of the FIR filter to produce the refined input stream.
