The paper presents its contribution to tracking control design of mechanical systems in underactuated mode conditions, i.e. when the number of actuators is less than the number of possible control inputs. Fully actuated mechanical systems are quite w

This paper presents a proposal for the use of energy indicators to evaluate the load modelling methods on the dynamics of a mobile crane. Three different variants of mathematical models of a load carried were examined and compared: as a lumped mass o

In the paper the dynamic analysis of a gantry crane used for transporting of BOP (BlowOut Preventer) is presented. The crane is placed on a drilling platform. Sea waves cause motion of the platform and the load. Description of such systems can be use

Abstract The general mathematical model of a flexible connection of links by means of spring-damping elements is presented in the paper. The formalism of homogeneous transformation matrices is used to derive formulas for the energy of spring deformat
