Abstract: For active vibration control applications, positive position feedback (PPF) type controller is quite suitable. These controllers are of low order so are easy to implement in practice. These controllers avoid the problem ...

Abstract: It is a well known fact that system parameters of the flexible structures keep on changing due to several reasons. Ordinary controllers lose their effectiveness in changed situations and do ...

Abstract: Rotors are used to transfer power from one component to the other component in various rotor dynamics applications like steam turbines, aerospace systems, and power generators. In certain applications, the seal is an ...

Abstract: This paper presents a novel concept of the modeling, active control of transverse vibration responses, and identification of fault parameters in a geared-rotor system integrated with active magnetic bearings (AMBs). The ...

Abstract: Air pollution poses a significant environmental challenge in many urban areas worldwide, largely driven by human activities and increasingly affecting air quality (AQ). This study focuses on mapping various pollutants that ...

Abstract: Vibration characteristics of a cracked Jeffcott rotor with an offset disk under the action of an active magnetic bearing (AMB), implemented to improve the radial positioning of the rotor, has been studied. Presence of the ...

Abstract: Acoustic agglomeration is proposed as an intermediate treatment in the flue gas cleanup train of the effluents from coal burning power plants. Acoustic agglomeration causes the micron and submicron ...

Abstract: It is well known that there is degradation in the performance of a fixed parameter controller when the system parameters are subjected to a change. Conventional controllers can become even ...

Abstract: The blank holder force (BHF), which regulates the amount of metal drawn into the die cavity, has been used effectively to draw defect-free sheet parts. It has been shown that a properly ...
