An H ∞ based robust controller is designed for a rate-feedback ow-control problem in single-bottleneck communication networks. The controller guarantees stability robustness to uncertain time-varying multiple time-delays in diierent channels. It also brings the queue length at the bottleneck node to the desired steady-state value asymptotically and satisÿes(More)
In this study, we conduct experimental and consecutive numerical analyses of a flapping tidal current generator with a mirror-type dual configuration with front-swing and rear-swing flappers. An experimental analysis of a small-scale prototype is conducted in a towing tank, and a numerical analysis is conducted by means of two-dimensional computational(More)
This paper presents how to use feedback controller with helicopter dynamics state space model. A simplified analysis is presented for controller design using LQR of small scale helicopters for axial & forward flights. Our approach is simple and gives the basic understanding about how to develop controller for solving the stability of linear helicopter(More)
The reliability of a navigation system is one of the critical requirements for air or automotive navigation. In order to increase the reliability of the navigation system, failures or faults resulting from the malfunctions of the system should be detected and repaired to keep the system possessing high integrity. This leads to a need for developing high(More)
This paper presents a design and analysis of electromechanical sigma-delta modulator for MEMS gyroscope, which enables us to control the proof mass and to obtain an exact digital output without additional A/D conversion. The system structure and the circuit realization of the sigma-delta modulation are simpler than those of the analog sensing and feedback(More)
