This paper deals an adaptive fault tolerant control for active suspension in the presence of actuator saturation. An adaptive state-feedback controller is designed to tackle the issue of actuator fault. A Disturbance observer is utilized to observe the lumped disturbance. The partial actuator fault or actuator inefficiency is consider as an actuator fault. The fault is estimated and then compensated...
This paper deals with reducing the vertical oscillations of the vehicle using active suspension. A full car model is considered with pitch and roll motion dynamics. Sliding mode control is used to control the nominal system matrices while the effect of disturbances from the road profile is suppressed through an inertial delay control (IDC) estimation technique. Global asymptotic stability of the controller...
This paper presents a state and perturbation observer based state feedback control for active suspension systems. The state and perturbation observer estimates the lumped disturbances as well as system states. The estimated states and disturbances are utilized in control law design. The performance of the proposed scheme is assessed with different road profiles in simulation and validated on experimental...
A solar tracker is a device which always faces sun throughout the day and 365 days a year. It is mainly used to track maximum energy from the Photo voltaic panel. In this paper, a three dimensional solar tracker has been implemented, which utilizes the sensor made with four LDRs (Light Dependent Resistors). Here a special arrangement of LDRs has been used which will enhance the working range of the...
Poly harmonic broadcasting is a variant of traditional harmonic broadcasting scheme which requires low bandwidth and less waiting time to provide video-on-demand service. Here a video is divided into segments of equal size and client STB starts downloading data from the time when customer requests a video instead of waiting until customer starts watching the first segment of the video. If a server...
