The previous reported relative navigation system designed for formation flight is applied to vehicle platooning. This system is based on both GPS (Global Positioning System) and millimeter-wave radar. This approach includes a federated Kalman filter.

With this control law, the guaranteed tracking precision has been shown to reduce at least by half, as compared with the conventional continuous sliding control. The error transient response during the reaching phase has also been remarkably improved by the proposed control. To illustrate its superiority, we presented a composite complementary sliding control scheme for a cascade uncertain nonlinear system, which includes the benchmark nonlinear problem, TORA. Simulation results on TORA showed excellent responses to any initial conditions and to single-frequency sinusoidal disturbances.","PeriodicalId":415046,"journal":{"name":"SICE 2001.

The authors propose a new type of motion capture system that uses rotating magnetic field for angular position detection and differential magnetic field for linear position detection.

AHS is an example of a large scale, multiagent complex dynamical system and is ideally suited for a hierarchical hybrid controller. We discuss the design of efficient hybrid controllers for the platoon maneuvers on an AHS. For the modeling of a hybrid system including the merge and split operations, we introduce the safety distance policy for the merge and split operations. Then, the platoon system is modeled by a hybrid system. In addition, the hybrid controller for the proposed merge and split operation models is presented. Finally, we demonstrate our scenarios for platoon maneuvers using the hybrid control scheme.","PeriodicalId":415046,"journal":{"name":"SICE 2001. Proceedings of the 40th SICE Annual Conference.

The frequency weighted Gramians are defined in the frequency domain which have frequency weighting factors to accentuate the input-output behavior of the interested states in some frequency range. The algorithm is basically based on a state weighting technique due to frequency weighted Gramians differently from other algorithms that weights inputs or outputs. The concerned state has more influence on the reduced system in the range of the frequency weighted, resulting in small model reduction errors with little sacrifice in performance.","PeriodicalId":415046,"journal":{"name":"SICE 2001.

An algorithm for finding excess factor, direction of sampling, and final estimates including signal frequency, amplitude, initial phase angle and magnitude of pedestal, is shown in detail. The technique combined with non-uniform sampling and the Prony method is evaluated by numerical experiments. The technique gives accuracy on each estimate, showing higher precision especially on higher frequency up to an extraordinary higher limit. Thus, the technique enables us to utilize slower A/D converters for higher frequency measurement, or to achieve extremely high frequency measurement with using faster A/D converters.","PeriodicalId":415046,"journal":{"name":"SICE 2001.
