Computation of the rms state variables and control forces in a half-car model with preview active suspension using spectral decomposition methods

Vibration control for active seat suspension systems via dynamic output feedback with limited frequency characteristic

“…This section is devoted to the problem of finite frequency H 1 controller design for the active seat suspension system in (2). We are interested in designing a dynamic output feedback controller, such that the H 1 norm of the closed-loop system is minimized over the chosen frequency range, while respecting the constraint in (5) within bound.…”

“…Therefore, good seat suspension systems can significantly enhance ride comfort, which makes the seat suspension control become a hot topic. Recently, combining active vibration control mechanism with advanced control algorithms to design and analyze suspension systems has been a popular and effective way, and attracted considerable attention [1,2,6,8,14,18,25]. The core idea is to use active control method in suspension systems to reduce the impact of disturbance.…”

Adaptive Fuzzy Wavelet NN Control Strategy for Full Car Suspension System

“…Various linear control techniques are applied on a quarter car model in (Bigarbegian et al, 2008) but did not give any information for large gain from road disturbance to vehicle body acceleration. The dynamic behavior and vibration control of a half-car suspension model is inspected by different researchers in (Hac, 1986;Krtolica & Hrovat, 1990;1992;Thompson & Davis, 2005;Thompson & Pearce, 1998).…”

“…These techniques were combined with wavelets to solve different control and signal processing problems and collectively known as Fuzzy Wavelet Neural Networks (FWNNs) (Chalasani, 1986;Hac, 1986;Heo et al, 2000;Meld, 1991;Thompson & Davis, 2005;Thompson & Pearce, 1998). The combination of a fuzzy wavelet neural inference system comprises the strength of the optimal definitions of the antecedent part and the consequent part of the fuzzy rules.…”

Random displacement and acceleration responses of vehicles with uncertainty

“…Numerous papers about the theoretical and experimental investigation on the dynamic behavior of passively and actively suspended road vehicles have been published [1][2][3]. The quarter-car model [2][3][4][5][6], half-car model [7][8][9] and full-vehicle model [10][11][12] have been developed with researches related to the dynamic behavior of vehicle and its vibration control. The simplest representation of a ground vehicle is a quarter-car model with a spring and a damper connecting the body to a single wheel which is in turn connected to the ground via the tire spring.…”
