The posture of the laser head is requested strictly in the cutting along the intersecting line of laser processing robot, and the position model of intersecting line is complex. In order to meet these demands, a continuous trajectory planning method which is used to controlling the position and posture of laser head is proposed. For the normal direction of the surface keeping coaxial to the laser...
Shift schedules both for optimal dynamic performance and fuel economy are proposed in this paper for vehicles equipped with dual clutch transmissions. A range simulation model for DCT vehicles has been established to evaluate the effects on dynamic performance and fuel economy. A fuzzy logic controller for engine throttle and a PID controller for brake force are used for vehicle operation. The simulation...
An ultra-precision vibration isolation platform composes of a mechanical structure and a feedback controller. Conventionally, these two elements are designed sequentially, with the controller design subsequent to that of the mechanical structure design. The traditional design method cannot obtain the global optimum performances for the system. This paper presents an approach to integrate structural...
