Optimisation-based clearence: the linear analysis

Kurzfassung

We present the clearance results of the HIRM+RIDE control configuration for the linear stability and handling criteria mostly used in the current industrial practice. The performed analysis is based on an optimisation-driven worst-case search. Two classes of linear stability related criteria are considered: the Nichols exclusion region based stability margin criterion and the unstable eigenvalues criterion. The considered handling criteria are the average phase rate and the absolute amplitude criteria. The analysis results clearly illustrate the high potential of the optimisation-based approach in reliably solving clearance problems with many simultaneous uncertain parameters.
