DESIGN METHOD, DESIGN SUPPORT APPARATUS, AND COMPUTER PRODUCT FOR FEEDBACK CONTROL SYSTEM |
摘要 |
A control system is designed in which a controlled plant is controlled based on output feedback from the controlled plant. An all-pass filter is modeled that is formed of a synthesis of a notch filter compensating for a resonance mode in the control system and the resonance mode. A design controlled plant including the all-pass filter is determined. A controller controls the design controlled plant and includes a weighting function, and, after the weighting function is derived, gain of the weighting function is adjusted using desired gain crossover frequency and phase margin. A phase variable included in a phase-lead weight is determined, and thus the weighting function is determined. H∞ loop shaping is applied to the weighting function and the design controlled plant to obtain an H∞ loop controller.
