This thesis focuses on the development of some fixed-order controller design methods in the
gain-scheduling/Linear Parameter Varying (LPV) framework. Gain-scheduled controllers …

For a magnetically suspended control moment gyroscope (MSCMG) with strong gyroscopic
effects, the nutation and precession stability control is an important part of system stability. In …

To overcome the singularity problem of control moment gyros (CMGs) and simultaneously
provide a lightweight, agile, and simple dynamical system, a CMG system called a double …

Control moment gyroscope (CMG) is an actuator commonly used in attitude control of
satellites and spacecrafts, as well as in stabilization of marine vessels and unmanned …

The advent of a Control Moment Gyro (CMG) system has a significant impact on the valid
powerful torque output for a three axis attitude control of a spacecraft. The accurate torque of …

Momentum exchange devices (MEDs) have been used for complete attitude control of
spacecraft as actuators, in which they do not require fuel. Among MEDs, reaction wheels …

The control moment gyroscope (CMG), which has the capability to produce large,
continuously adjustable torques, is a key attitude control actuator for a spacecraft. The rotor …

The proportional-integral (PI) controller has proven to be a remarkably effective control
strategy in the servo field. However, it is difficult for PI to handle the problem of multiple …

In the operation of CMGs there exists a concept called “back drive,” which represents a case
where the coupling effects of the angular velocity of the body and the angular momentum of …

This paper proposes a novel linear quadratic regulator (LQR) weight selection algorithm by
synthesizing the algebraic Riccati equation (ARE) with the Lagrange multiplier method for …
