Unbalance Control of Rotating Ill-Balanced Mass System

Cascade Control System for Two Axes Gimbal System with Mass Unbalance

the application of inertial stabilization system is to stabilize the sensor’s line of sight toward a target by isolating the sensor from the disturbances induced by the operating environment. The aim of this paper is to present two axes gimbal system. The equations of gimbals motion are derived using Lagrange equation considering the base angular motion and mass unbalance. The stabilization loo...

Rotor’s Mass Unbalance Compensation Control on Bearingless Permanent Magnet Synchronous Motors for Minimizing the Control Currents

The vibration originated from the rotor’s unbalance mass impacts on the current oscillation. When the rotor rotating at high speed, power amplifier circuit will be burned down by excessive vibration control current, and at the same time the excessive control force will be generated. The vibrating force transfers to frame, which causes the system vibration and influence the dynamic properties an...

Constrained Quadratic Programming, Active Control of Rotating Mass Imbalance

Jet engines may experience severe vibration due to the sudden imbalance caused by blade failure. The current research investigates employment of piezoelectric actuators to suppress this using active vibration control. This requires identification of the source of the vibrations via an expert system, determination of the required phase angles and amplitudes for the correction forces, and applica...

the ill-balanced triangles of the islamic states in crisis

policy implementation is among the most   important stages in the policy cycle (lester et al., 2000:5). policy-makers know well that this stage is so essential that can affect all aspects of politics in local, national and international levels. despite this fact, policies implemented do not have often the desired results. this article tries to analyze this phenomenon in the islamic states using...
