Linear and Nonlinear Controller Contrast for the Vibration Isolation System
The analysis of smart spring vibration isolation system is analyzed through MATLAB simulation. The results show suppressing dominant vibration mode of platform. In the paper controllers developed for the smart spring are linear and nonlinear. This paper deals with MIMO system analysis of low frequency dominant modes, which are critical, examined first by linear controller techniques and then wi...
متن کاملLinear Parameter-varying Control for Active Vibration Isolation Systems with Stiffness Hysteresis
We consider the use of linear parameter-varying methods for the control of stiffness hysteresis in vibration isolation systems. We assume that the hysteresis model is known, and we describe it using a stiffness parameter that takes values in a compact convex set. The proposed parameter-dependent controller is continuously scheduled based on real-time measurements or estimates of the stiffness, ...
متن کاملVibration Isolation via Linear and Nonlinear Periodic Devices
The current manuscripts deals with the design of passive mechanical filters for vibration attenuation a low frequencies. Traditionally, this has been addressed employing dissipation as the attenuation mechanism. While such strategy provides broadfrequency effectiveness, attenuation at any given frequency is modest. Mass and stiffness-modulated periodic systems, on the other hand, exploit disper...
متن کاملActive Vibration Isolation of Multi-Degree-of-Freedom Systems
One of the principal objectives of vibration isolation technology is to isolate sensitive equipment from a vibrating structure or to isolate the structure from an uncertain exogenous disturbance source. In this paper, a dynamic observer-based active isolator is proposed that guarantees closed-loop asymptotic stability and disturbance decoupling between the vibrating structure and isolated struc...
متن کاملApplication of Compliant Mechanisms to Active Vibration Isolation Systems
Compliant mechanisms have been designed for various types of applications to transmit desired forces and motions. In this paper, we explore an application of compliant mechanisms for active vibration isolation systems. For this type of application, an actuator and a compliant mechanism are used to cancel undesired disturbance, resulting in attenuated output amplitude. An actuator provides exter...
