The surging popularity of adopting industrial robots in smart manufacturing has led to an increasing trend the simultaneous improvement energy costs and operational efficiency motion trajectory. Motivated by this, multi-objective trajectory planning subject kinematic dynamic constraints at multiple levels been considered as a promising paradigm achieve improvement. However, most existing model-based optimization algorithms tend come out with infeasible solutions, which results non-zero...
This paper takes 30,000-ton heavy-haul trains as the research object, and studies propagation characteristics, train braking ability longitudinal impulse level of three ECP electronic control signal Propagation modes segmented electro-pneumatic under different lag times. The difference between train’s use air in long ramp operation method is compared. results show that best way when leading locomotive sends backward slave both forward backward. Compared with worst mode only propagates...
To investigate the influence of lag time in braking response slave control locomotives caused by LOCOTROL wireless synchronous system on longitudinal impulse train, a 30,000-ton heavy-haul train model was established. The is form '1+1+1+1'. simulation accuracy air verified comparing with static tests. A dynamic consisting two HXD1 and 100-type couple established for study middle locomotive's running safety. Results show that, under normal transmission delays, approximately 2–3 s....
Purpose The purpose of this paper is to enhance control accuracy, energy efficiency and productivity customized industrial robots by the proposed multi-objective trajectory optimization approach. To obtain accurate dynamic matching torques robot joints with optimal motion, an improved model built a novel parameter identification method has been proposed. Design/methodology/approach This proposes approach minimize time consumption trajectory. First, authors develop reliable parameters joint...
Purpose Sensorless passive lead-through programming (LTP) is a promising physical human-robot interaction technology that enables manual trajectory demonstrations based on gravity and friction compensation. The major difficulty lies in static compensation during LTP start-up. Instead of compensation, conventional methods only compensate for Coulomb after the joint velocity exceeds threshold. Therefore, start-up external torques must overcome friction. When considerable, it difficult to start...
