FREQUENCY-SHAPING LQ CONTROL OF MAGLEV SUSPENSION SYSTEMS FOR OPTIMALPERFORMANCE WITH DETERMINISTIC AND STOCHASTIC INPUTS

Methods for achieving target performance specifications for suspension controllers on low-speed Maglev vehicles using linear quadratic (LQ) control are examined, In particular, a technique involving frequency-d omain weightings in the performance criterion integral to reach perfor mance targets simultaneously for stochastic and deterministic inputs i s investigated. It is shown that good performance is obtained with the added benefit of obviating the vexed problem of estimating criterion integral weightings in conventional LQG control design.
