| Summary: | One of the major problems associated with H-infinity
controller design is the challenges of weighting function
parameters’ tuning. For a given control problem, it is
requires to select appropriate weighting function
parameters to satisfy both the stability requirement and
time domain specifications. The conflicting nature of
these objectives has made such design exercise a tedious
endeavor. In this study, the optimal-tuning of the Hinfinity
controller parameters using multi-objective
differential evolution (MODE) technique is proposed,
and apply for control of a two-mass-spring system
which represents a typical benchmark robust control
problem. The performance of the resulting robust
controller is evaluated both on the nominal plant and
perturbed plants with parameter variation. The
simulation results indicate a good compromise between
the robustness and time domain performance. |
