Active Stabilization of Thermoacoustic Oscillation
… problems which can be overcome by the use of active control. This thesis addresses the problem of actively controlling thermoacoustic instabilities in a laboratory test com- bustion chamber. Different strategies for actuation are discussed and evaluated experimentally. Relations to industrial …

Control Design for an Inertially Stabilized Rifle
… through the design and implementation of a active stabilization system for small arms weapons. The INSTAR system is an innovative active stabilization system designed to decouple the shooter's disturbance effects from the barrel movement. The INSTAR system uses an piezoelectric actuator …

Mini Cheetah Sensor Suite for Visual Perception
… mini cheetah robot and does not incorporate any active stabilization into the design. A lightweight sensor suite was designed and manufactured incorporating a commercial gimbal. Three tests were conducted on a rigid mounted camera and a gimbal stabilized camera. AprilTag detection as well as …

Dynamic characterization and active control of unstarts in a near-isentropic supersonic inlet
… and engine-born disturbances, necessitating active control. An active stabilization bleed system is introduced that recovers the disturbance-rejection capabilities required of modem inlets. The bleed system requires 4% steady state bleed and up to 6% additional unsteady bleed for active …

Stabilization of a roll-tilt camera on an autonomous quadrotor helicopter
… for implement- ing servo motor controlled camera stabilization on these autonomous vehicles. The need for camera stabilization arises because video footage is monitored continuously while the onboard GPS is controlling the motion of the quadrotor. The operator of the quadrotor may not want to look …

Efficient ranging-sensor navigation methods for indoor aircraft
… (IMU) onboard a quadrotor helicopter to enable active stabilization and position control. Two different navigation algorithms that utilize a scanning laser and techniques borrowed from Simultaneous Localization and Mapping (SLAM) are evaluated for use with an IMU-stabilized flying vehicle. …

Enhancing human metabolic economy in stair climbing via an elastic crutch mechanism
… electromyographic (EMG) signals from the primary active muscles provides a neuromuscular interpretation of the crutching activity not captured by the black-box metabolic techniques. We complete the picture by modeling the energetics of the effective elbow muscle by incorporating empirical …
