Experimental Modelling and Control of a Tower Crane in the Frequency Domain

Abstract

The laboratory tower crane by INTECO is used in research and education of control engineering for mechatronics. Its modelling and control include several subsystems. The paper deals with identification of dynamic model of trolley motion along the jib and trolley position controller design, as well as design of compensator to damp payload oscillations in the direction along the jib. A thorough frequency domain analysis of obtained results is provided.
