Abstract-This paper is concerned with the problem of fault detection filter for vehicle active suspension systems. The aim of this paper is to design a fault detection filter in finitefrequency domain. A sufficient condition for residual system with the prescribed H∞ performance index is derived based on the generalized Kalman-Yakubovich-Popov (KYP) lemma. In view of the obtained condition, the fault detection filter is designed in middle-frequency domain. Simulation results show the effectiveness and potential of the proposed results.Index Terms-Finite-frequency domain. Fault detection. Filter design. Vehicle active suspension systems.

This study is concerned with output-feedback H-infinity controller synthesis in finite frequency domain for continuous-time multi-channel linear systems. The recently developed results of full-order centralised H-infinity control theory in this field are extended to the subject of decentralised control. Both the block-diagonal reduced-order dynamic and static controller designs are discussed in a unified manner. Sufficient solvability conditions are given in terms of linear-matrix-inequalities. A numerical example is provided that establishes the efficacy of the proposed controller syntheses. IntroductionRecently there is a renewed interest in the field of H-infinity loop shaping [1] in which the design objective is to synthesise a stabilising controller to fulfil multiple frequency domain specifications set on various restricted frequency ranges. A novel approach capable of achieving this goal without introducing weighting functions into its design procedure has been developed. This approach is based on the so called generalised Kalman-Yakubovich-Popov (GKYP) lemma [2], initiated by the pioneer work of Iwasaki and his collaborators [3] in 2000. In recent years more and more theoretical results pertinent to this powerful tool have been established, for example model reduction [4], computation issues [5] and feedback controller synthesis [6-10], to name a few. On the other hand, an increasing number of engineering applications have been explored in diverse fields, for examples, disturbance rejection [11], track following control [12], active suspension systems [13, 14], fault detection [15], fuzzy filter design [16], quantisation noise reduction in uncertain cascaded sigma-delta modulators [17] and image coding [18].Focusing on the topic of feedback control synthesis in this field, to the best of the author's knowledge, the existing results (derived via the GKYP lemma) deal with either single-input-single-output cases or provide only centralised controller designs for multi-inputmulti-output systems. There has not yet an article of this field addressing structural control design. This motivates us to devote ourselves to this problem.On the subject of decentralised H-infinity control, in sharp contrast with the absence of work in the field of finite frequency decentralised control, there are profound results in the full frequency domain, see for example [19][20][21][22][23][24][25] and the references therein. Two major problem formulations have been addressed in literature. A typical class of problems deal with designing a decentralised stabilising controller such that a certain closed-loop transfer function satisfies a given H-infinity performance level over the entire frequency range (see e.g. [19-21] and references therein) or determining optimal decentralised H-infinity controllers under the so-called quadratic invariance assumption (see e.g. [22,23] and references therein). In the second class of problems the aforementioned problem is considered with an additional order constraint imposed upon the local contro...

This study presents a new robust filtering method in modelling an active multisensory suspension system with measurement delays and parameteric uncertainties in a state-space dynamical model. To achieve good performance of the system, a new distributed fusion receding horizon filtering frameworks are constructed to couple the continuous dynamics with the multisensory discrete measurements, and to coordinately deal with the parametric uncertainty and time-delays. The novel filtering algorithm is proposed based on the receding horizon strategy, standard mixed continuous-discrete Kalman filtering and discrete Kalman filtering for systems with time-delays in order to achieve high estimation accuracy and stability under parametric uncertainties. The key theoretical contributions of this study are the derivation of the error cross-covariance equations between the local receding horizon filters in order to compute the optimal matrix fusion weights. The high accuracy and efficiency of the new filter are demonstrated through its implementation and performance and then compared to the existing vehicle active suspension system.
