This paper presents a multiple-fan wind tunnel based on active control technology. The wind tunnel has 6 swivel plates which can rotate in −90°∼+90° at the entrance. Each swivel plate consists of 8 fans. The wind field in the wind tunnel can be changed by controlling the fan speeds and the angles of swivel plates. We use a master-slave control structure, instead of the previously used lumped structure,...
This paper presents a Takagi-Sugeno (T-S) model based fuzzy control design approach for rigid satellite attitude maneuver. The T-S fuzzy model is first applied to represent the rigid satellite model consists of dynamic and kinematics equation. Then, a fuzzy state feedback controller is designed for the obtained T-S fuzzy model with considering the decay rate by using the parallel distributed compensation...
In order to ensure the electricity output quality of one turbocharged diesel generator set under pulsed load, some measures were taken to control the speed regulating rate of original power machine. One main reason causing the big diesel speed regulating rate in experiment is the lack of air for combustion in the early period of pulse. The other reason is that the energy stored by set shafting parts...
The odor source localization using a mobile robot in time-variant airflow-field environment is considered. A novel estimation-based plume tracing method is proposed in this paper. Based on the odor-patch path estimated by the flow information when odor clues are found, a searching route is planned for the mobile robot to trace the plume. To have fair and statistic comparisons with both the spiral-surge...
At present, odor sensors and anemometers are simply used by most chemical plume tracing algorithms to measure the concentration and wind speed/direction, respectively. To make full use of the information of concentration and wind for chemical plume tracing, the concept of virtual odor-source-probability sensor (VOSPS) is put forward. The VOSPS adopts the data of odor sensor and anemometer as input...
