SYNTHESIS OF A STATE-FEEDBACK CONTROLLER TO SUPPRESS STRUCTURAL VIBRATIONS OF AN OVERHEAD CRANE
Abstract
A state-feedback controller is designed on the basis of simplified linear model of overhead crane flexible
framework in order to suppress its elastic vibrations. It is shown that standard polynomial synthesis algorithms for a
2D-controller ensure the optimized behavior of the elastic force applied to the trolley, while the input forces are kept at
non-zero constant values during movement with constant speed. The presented synthesis of two 1D-controllers allows to
avoid the mentioned drawback.
