Motion effector controller for use in a virtual reality system

摘要

In a motion effector for use in a virtual reality system, a plant is a target of control and for producing an output signal reflecting the actual movement of a moving part therein and a reference input provider provides a reference input signal which reflects a desired motion of the plant. In addition, a subtractor produces an error signal by subtracting the output signal from the reference input signal. A feedback compensator generates a first control signal by using the error signal and a feed-forward compensator generates a second control signal by using the reference input signal. An adder generates a final control signal by adding the first and the second control signals and provides the final control signal to the plant, wherein the final control signal is used to control the plant.
