2024 The PhD thesis is devoted to the development of improved controlsystems for crane electric motor drives. Based on the observed practicalproblems from the long-time exploitation of cranes and considerationof existing solutions, the dissertation proposes several innovativealgorithms and technical realizations. Among other things, somethingthat will be proposed is: a new algorithm for the skew control of a widespancrane construction, which can be easily implemented in existingdrives with minimal hardware upgrade; a new realization of thealgorithm for the load sharing between motors of controlled multimotordrive, which can be easily implemented in existing driveswithout a hardware upgrade; a new method for the motor selection anda new control algorithm for the monospiral cable reel drive; oneimprovement of the known industrial solution for optimizing thegenerator mode of motor operation of the complete crane drive system.All mentioned above is the result of detailed mathematical andsimulation analysis and/or detailed problem analysis, and afterpractical implementation, it was verified by experimental tests andrecordings of characteristic quantities.
