The 'dynamic tuning' of a dynamically tuned gyroscope (DTG) refers to a clever gimbal configuration that balances the torques from the support flexures with dynamic spring torques created by gimbal 'flutter' while the gyro rotor spins. This configuration allows the gyro rotor to spin to a 'free' rotor in two axes. The dynamics of a free rotor are widely known and easily summarized in the right-hand rule for gyro precession and a simple second order system equation with a natural frequency… 
Dynamic modeling, control and experimental validation of gimballed sensor system for precision pointing applications
TLDR
The comparative analysis suggests that, although both the control configuration satisfies the required accuracy, Fuzzy logic control certainly improvised the performance of the gimballed sensor system and hence can be very effective for more precise pointing, tracking and stabilization application.
Modeling and Error Analysis of Dynamically Tuned Gyroscope Based on Bond Graph
Bond graph method is a unified graphic method for modelling of engineering systems in several different energy domain. The open loop system of a Dynamically Tuned Gyroscope (DTG) is modelled using
Neural-fuzzy controller configuration design for an electro-optical line of sight stabilization system
TLDR
A Neural-fuzzy model structure to improve the disturbance attenuation performance of a gimballed Line of Sight (LOS) stabilization system and the comparative analysis suggests that the proposed Neural- fuzzy controller completely outperforms the FLC configuration and can be very effective for more precise pointing applications.
STABILIZATION OF A GIMBAL SYSTEM USING PID CONTROL AND COMPENSATOR - A COMPARISON
TLDR
This paper shows which of the two design techniques is a better choice for the given gimbal system.
Precision gimballed mirror control in remote sensing LIDAR for environmental monitoring
Differential Absorption Lidar (DIAL) Systems are advantageously used to detect and measure very small concentrations of trace gases in the atmosphere. There is a requirement to interrogate and search
Crash Detection Using IMU Sensors
TLDR
This document explains how to use the MPU6050 IMU sensor in an embedded device for measuring the Euler angles (roll, pitch, yaw) and also the G Forces on different axes.
Design of Carryable Intravenous Drip Frame with Automatic Balancing
TLDR
A reliable balanced system can be applied to facilitate patients’ movements and ensure patient safety with compensating the inclination angle of the drip frame such that the reduction of blood returning and the balance control of the piggyback intravenous drip frame can be achieved.

TLDR
How the BMI framework aids in analysing is shown along with how top-down and bottom-up processes are to be involved in behaviour recognition; additionally, how the framework supports the identification of information fusion at different abstraction layers is shown.
