Various control applications such as aerospace vehicles and automotive control systems can benefit from lower weight and cost. Replacing wired feedback control with wireless sensor and actuator networks (WiSAN) offers attractive features by improving upon the weight and cost problems, while posing new challenges due to the delayed noisy feedback links. Addressing these challenges requires modeling...
Network design for real time control of launch vehicles need to consider latency and noise in wireless environments. The proposed system will gather the acceleration information received from multiple sensors to reliably and robustly relay the orientation of the rocket back to the actuator system. To do so, a network simulation software will give us an estimate of the efficiency of these sensors in...
This paper presents a simulation study of the realtime determination of the elastic mode characteristics (frequency and displacement mode shape) of a launch vehicle using an array of sensors that measure the local strain along the length of the vehicle. The determination of the frequency and shape of the excited modes is accomplished using the buffered strain data. We assume that the sensed data is...
