In this paper, we use the NCTUns network simulator to study intelligent traffic signal control algorithms. NCTUns is both a microscopic traffic simulator and a network simulator. We imported the real-life map of a district of the Taipei city into NCTUns to let simulated vehicles move on the roads of the imported map. Then, we used a new and unique feature of NCTUns - each simulated vehicle moves towards...
LQG and LQI control theory were used to control the suspension system of the vehicle. We analyzed the characters of the system through simulation, and found that, with the LQI control algorithm, ride comfort and dynamic deflection can be improved simultaneously at the natural frequency of the weight on the spring. While with the LQG control algorithm cannot bring about that. But with LQG control,...
Tracking reentry vehicle with strong maneuvers on-line is a challenging task. The key is to develop suitable dynamic models and estimation methods. Two kinds of modeling methods are discussed for reentry tracking, and the unscented filter (UKF) is introduced to the nonlinear tracking system. To reduce the computational load, three simplifications of UKF are developed. Furthermore, the feasibility...
