Abstract
The energy efficiency of high-dynamic servo drive applications often provides opportunities for improvement, since regenerative energy is mostly dissipated via brake choppers and is lost for later demands. Therefore, this paper discusses different methods for the energy demand and peak load reduction of DC-link coupled multi-axis servo drive systems by application of mechanical and electrical energy storage. Experimental results show that idle system axes can effectively be utilized for regenerative energy buffering to improve the system efficiency instead of applying expensive energy storage systems. Therefore, an extended model-based approach for the control of a rotational mechanical storage axis during high dynamics motion tasks of general multi-axis servo drive systems is presented. For comparison, the utilization of commercially available electrical capacitive storage extension is investigated. All methods are applicable to arbitrary multi-axis servo drive systems, including robotic manipulators, without adaption of the motion sequences.
