ABSTRACT:
Herein disclosed according to the present invention are method and apparatus of two-degrees-of-freedom time difference comparison compensator. In a control system using a conventional regulator, a desired value or reference value is inputted to the regulator through a versatile time difference compensator. The apparatus may be constructed in the form of a versatile control apparatus to be realized as a hardware, a software or a composite having the two functions, an exclusive control apparatus, or a built-in control apparatus for an individual control system. Thus, the control system to be provided has an excellent effects in the relevant industry because it can make adjustments to the highest state while satisfying several characteristics such as the quickness of response and the stabilizability of perturbations or other several characteristics such as robust stabilizability simultaneously.
