Active automotive engine vibration isolation is considered where both stationary and transient engine-induced excitations as well as plant non-linearity are considered. The adopted control strategy targets the dominating spectral components of the excitation and achieves narrow band vibration isolation using feedback of disturbance states estimates. Time-varying gain-scheduled observer design, ...

The vibration stability requirements for the Next Linear Collider (NLC) are far more stringent than for the previous generation of Colliders. To meet these goals, it is imperative that the effects of vibration on NLC Linac components from near-field sources (e.g. compressors, high vacuum equipment, klystrons, modulators, pumps, fans, etc) be well understood. The civil construction method, wheth...

rotating machines in particular induction electrical machines are important industry instruments. in manufacturing, electrical motors are exposed to many damages, and this causes stators and rotors not to work correctly. in this paper we addressed modal analysis and an intelligent method to detect motor load condition and also the stator faults such as turn-to-turn and coil-to-coil faults using...

Abstract Balancing a bipedal robot movement against external perturbations is considered challenging and complex topic. This paper discusses how the vibration caused by disturbance has been tackled Linear Quadratic Regulator, which aims to provide optimal control system. A simulation was conducted on MATLAB in order prove concept. Results have shown that linear quadratic regulator successful st...
