Control Allocation Investigation:Sampling Rate Selection.

摘要

One of the major considerations facing the design of high performance automated transit systems is the efficient and economical allocation of the control functions between the transportation vehicle and a digital computer located at the wayside. The report examines the non-emergency control of vehicle speed and spacing (i.e.,the vehicle regulation problem). The primary goal is to identify the type of information and the rate at which this information must be exchanged across the vehicle/guideway interface in order to achieve precise vehicle regulation. A successful system design keeps the communication requirements within the available channel capacity. The effect of control allocation on these requirements is examined by varying the complexity of the onboard vehicle control system.
