演讲摘要:

In this talk, some research activities at the Robotics, Automation, and Mechatronics (RAM) Lab at Rutgers are presented. The first part of the talk will focus on some research activities in the vehicle and transportation area. Two subjects will be discussed: safety-preserved tire/road interaction estimation and control, and macroscopic traffic flow stability. Tire/road friction characteristics determine the vehicle’s safety limits and need to be monitored and estimated on-line for vehicle safe operations. Two different schemes for on-line estimation and control of the tire/road friction coefficient will be presented. An attractive property of these two approaches is that the estimates of the maximum friction coefficient and slip remain below their true values, which, in turn, guarantees safety of the vehicle spacing policies. Some ongoing work on the development of a “smart tire” system will be discussed. At traffic flow level, some results on macroscopic traffic flow stability will be presented. A wavefront expansion technique is applied to establish a traffic flow stability criterion for both manual and adaptive cruise controlled vehicles. The second part of the presentation will discuss a design of vision-based motion planning and trajectory tracking control of an autonomous motorcycle. A vision vector space, a unitary vector set that represents local collision-free directions in the image coordinate system, is constructed for the highly dynamic requirements of motion planning of an autonomous motorcycle. A balance and trajectory tracking control algorithm for the autonomous motorcycle is then presented. The planning and control systems are validated by experimental and numerical testing based on a real prototype motorcycle system. Other research topics in the RAM Lab will also be discussed briefly at the end of the presentation.
