“…As it can be observed from the summarized literature, papers that address the controller design which uses only easily measurable variables such as acceleration and velocity signals are very few. Between these listed papers, the results of Du et al, 8 Du and Zhang, 10 Da Silva et al, 24 Sever and Yazici, 25,26 Ning et al 27,28 and Du et al 29,30 are very interesting and promising since significant improvements are obtained in terms of disturbance mitigation of vehicle suspension systems when compared to some existing studies in literature. However, L 2 gain output derivative feedback control problem is not considered and applied on vehicle suspension system to mitigate road-induced vibrations as provided in this article.…”

In this article, we present a novel approach to design an L2 gain output derivative feedback controller for active vibration control of a vehicle suspension system. In vibration control problems, state derivative signals such as acceleration and velocity are easier to obtain rather than the state variables such as position and velocity, since the accelerometers are simpler, cheaper and more reliable than position sensors. First, an L2 gain output derivative feedback controller is proposed by taking into account that measuring state derivative signals belong to driver body and electro-hydraulic actuator is not applicable in practice. Then, an L2 gain state derivative feedback controller and an L2 gain static output feedback controller are designed to investigate efficacy of the proposed controller. Performance of the controllers is tested against bump- and random-type road irregularities. A 4-degree-of-freedom integrated vehicle suspension model that includes a quarter vehicle suspension, a seat suspension, a driver body and an electro-hydraulic actuator is used throughout the numerical simulation studies. Simulation results show that proposed L2 gain output derivative feedback controller provides compatible performance improvement in the state derivative feedback control and static output feedback control with more viable feedback strategy.

This paper concerns with the optimal state derivative feedback LQR controller design for vibration control of an offshore steel jacket platform having active tuned mass damper against the wave induced disturbances. Considering that the state derivative signals such as acceleration and velocity are easier to measure rather than the state variables such as displacement, state derivative feedback control strategy is proposed to obtain practically applicable and easily realizable synthesis method. On the basis of convex optimization approach, state derivative feedback LQR controller design is formulated in Linear Matrix Inequalities (LMIs) form to get an optimal feasible solution set. Finally, an offshore steel jacket platform subject to nonlinear self excited wave force is used to illustrate the effectiveness of the proposed approach through simulations. The results show that proposed state derivative LQR controller is very effective in reducing vibration amplitudes of each floor of modeled offshore steel jacket platform and achieves compitable control performance to classical LQR controller design.

“…A state derivative feedback controller having regional pole location constraint was applied to an experimental quarter vehicle active suspension system [26]. In order to design an active suspension controller for an integrated suspension system, an L2 gain state derivative feedback controller has been proposed by Sever and Yazici [27]. Thereafter, the L2 gain state derivative feedback controller has been extended with robustness property for the systems having polytopic type uncertainties by Yazici and Sever [28].…”

This paper is concerned with a control design of an electro-hydraulic suspension system. In some practical problems, for instance in the active suspension design, the state derivative signals such as acceleration and velocity are easier to obtain rather than the state variables such as displacement and velocity, since the most commonly used sensors are the accelerometers. Hence, design of an optimal state derivative feedback controller is proposed by employing the linear matrix inequalities framework. In order to demonstrate the effectiveness of the proposed controller, a two-degree-of-freedom quarter vehicle suspension model equipped with an electro hydraulic actuator is preferred. Throughout the numerical simulation studies, bump type road irregularities at different vehicle forward velocities are applied to evaluate the performances of the controller in terms of ride comfort and safety.
