DESIGN METHOD, DESIGN SUPPORT APPARATUS, AND COMPUTER PRODUCT FOR FEEDBACK CONTROL SYSTEM

摘要

A design method, a design program, and a design support device for a feed back control system are provided to implement a robust actual system and obtain a stable system. An all-pass filter composing a notch filter and a resonance mode is modeled(S105). A control object for designing including the all-pass filter is determined(S106). A weighting function included in a controller is extracted(S111). A gain of the weighting function is controlled by using a target gain cross frequency and a phase margin(S112). The weighting function is decided by determining a phase variable included in a phase lead weight(S113). An H-loop forming method is applied to the control object and the decided weighting function(S114). The H-loop controller is extracted(S115).
