This article proposes a novel control method for vehicle active suspension systems in the presence of time-varying input delay and unknown nonlinearities. An system dynamics estimator (USDE), which employs first-order low-pass filter operations has only one tuning parameter, is constructed to deal with With this USDE, widely used function approximators (e.g., neural networks fuzzy-logic systems) are not needed, intermediate variables observer traditional estimators required. reduced...
To improve the positioning accuracy of industrial robots and avoid using coordinates end effector, a novel kinematic calibration method based on distance information is proposed. The model an robot established. relationship between moving effector parameters analyzed. Based results analysis robot, error with displacements as reference built, which linearized for convenience following identification. singular value decomposition (SVD) used to eliminate redundant model. solve problem that...
Optimization for vertical vibration performance of a rail‐train coupling system is investigated in this paper with the introduction inerters both primary and secondary suspensions. A model typical Chinese passenger train that travels on traditional rail track, sleepers, ballast simulated. The goal to improve ride quality attenuation response track irregularities. Optimizations only inertance all suspension parameters are carried out by particle swarm algorithm (PSO). Performance benefits...
Intelligent methods and algorithms have promoted the development of intelligent transportation system in many ways. In rail transportation, vertical performance a high-speed train suspension has great impact on riding comfort train. Based optimization method particle swarm (PSO) algorithm, different inerter-spring-damper (ISD) layouts are proposed for better comfort. A 10-degree-of-freedom (10-DOF) dynamic model is established, new applied to primary secondary at same time. Optimizations...
