In this work, we revisit the linear gyro-kinetic theory of geodesic acoustic modes (GAMs) and derive a general dispersion relation for an arbitrary equilibrium distribution function ions. A bi-Maxwellian ions is then used to study effects ion temperature anisotropy on GAM frequency growth rate. We find that yields sensible modifications both rate as tend increase with these results are strongly...

–A flight path rate demand modified three-loop lateral missile autopilot design methodology for a class of guided missile, based on state feedback, output feedback, reduced order Das & Ghosal observer (DGO) is proposed. The open loop undamped model of three-loop autopilot has been stabilized by using pole placement and state feedback. The non-minimum phase feature of rear controlled missile air...

In this thesis report, the theory of MEMS vibratory gyroscope is introduced and discrete wavelet decomposition and reconstruction are introduced. In the first part of this work, I review the Coriolis effect and angular rate sensors, and fundamental operational principles of micro-machined vibratory gyroscopes. The MEMS gyroscopes are expected to lead to reliable, robust and high performance ang...

This paper presents an approach for realizing a phase difference measurement of a new gyro. A silicon micromachined gyro was mounted on rotating aircraft for aircraft attitude control. Aircraft spin drives the silicon pendulum of a gyro rotating at a high speed so that it can sense the transverse angular velocity of the rotating aircraft based on the gyroscopic precession principle when the air...
