APPARATUS AND METHOD FOR CONTROL OVERHEAD CRANE

摘要

PURPOSE: An overhead travelling crane control device and a method are provided to reduce the stabilization time of a system. CONSTITUTION: An overhead travelling crane control device(200) comprises a sliding surface equation inducing unit(210) which defines a second level sliding surface by linearly combining multiple first level sliding surfaces expressed by using the error between an actual output value and an desired output value in the sliding mode control, a signal input section(220) which offers an input signal using a finite time control method on the second level sliding surface, and a controller(230) which controls an overhead travelling crane(240) according to the condition of a sub system which is calculated in the sliding surface equation inducing unit. The first level sliding surfaces include a first sliding surface and a second sliding surface.
