Robust Gain-Scheduling Controller to LPV System Using Gap Metric

摘要：

The gain-scheduling was a good choice for dy- namic systems whose operation range were very large,when the dynamic systems were turned into linear parameter varying sys- tems (LPV)through appropriate states transform.The method of designing robust gain-scheduling to LPV system based on polytopic was studied,and a new scheduling strategy was proposed because of the conservatism of the scheduling strategy based on varying parameter s position.The new scheduling strategy was based on gap metric.From simulation result,we can see that the new strategy can reduce overshoot by about 10%,and can reduce the controller maximal output by about 30%,and can restrain states oscillation compared with the old strategy.
