Control system design for an ideal transient control performance—proposal of simulator‐based foresight control

A new concept to achieve an ideal transient control performance is described. It is also possible to examine control performance on the frequency domain. Generally speaking, better control performance will be realized by using more exact information on the plant. A simulator should be built that has both correct initial values of state variables and parameters on dominant parts of the plant. The internal states of the simulator are used to represent the internal states of the plant, and control input is synthesized with the internal states of the simulator and the plant output. Using information on the simulator allows an ideal control performance at a dominant frequency area to be obtained in spite of the existence of unmodeled dynamics at a higher frequency domain. This control system is called simulator-based foresight control (SFC), and is available for both nonlinear and timevarying plants.
