This study focuses on a challenging issue of reduced-order observer-based fault estimation for a class of nonlinear continuous-time systems with both unknown inputs and model uncertainties. By introducing a nonsingular coordinate transformation, a new nonlinear reduced-order fault estimation observer (RFEO) is proposed, which not only expands the application range of existing fault estimation observers, but also to achieve the accurate estimation of both states and faults. Simulation results of an aircraft application are presented to validate the effectiveness of the proposed methods.

For Multi-Level Cell (MLC) NAND flash, which is a main-stream product with two bits per cell, redundancy method has been widely adopted to enhance the reliability of the system data. In particular, it is used to enhance metadata reliability because the damage of metadata may cause the system to crash and a large amount of data to be lost. However, for MLC NAND flash with asymmetric distribution of bit errors between least significant bit (LSB) pages and most significant bit (MSB) pages, the arbitrary distribution strategy for replicas of the traditional redundancy method will degrade of effectiveness of the redundancy method. This paper presents Asymmetric Redundancy method, an enhanced redundancy strategy for MLC NAND flash memory storage systems. Our technique for the first time exploits the property of the multi-page architecture of MLC NAND flash memory to change the allocation of metadata and its replicas. We can achieve much more reliable storage system compared with traditional redundancy methods. We have implemented Asymmetric Redundancy on a real hardware platform. The experimental results show that Asymmetric Redundancy can reduce uncorrectable page errors by up to 98.33% and 81.13% compared to baseline and Meta-Cure, respectively.

Representing images and videos as linear subspaces for visual recognition has made a great success which benefits from the Riemannian geometry named the Grassmann manifold. However, subspaces in vision are high-dimensional, which leads to a high computational expense and limited applicability of existing techniques. In this paper, we propose a generalized model to learn a lower-dimensional and more discriminative Grassmann manifold from the high dimensional one through an orthonormal projection for a better classification. We respect the Riemannian geometry of the Grassmann manifold and search for this projection directly from one Grassmann manifold to another face-to-face without any additional transformations. In this natural geometry-aware way, any metric on the Grassmann manifold can be resided in our model theoretically. We have combined different metrics with our model and the learning process can be treated as an unconstrained optimization problem on a Grassmann manifold. Experiments on several action datasets demonstrate that our approach can improve a more favorable accuracy over the state-of-the-art algorithms.

To solve the problem of machining error caused by the analytical method of focusing cam of aeronautical remote sensor, a new method of cam processing error calculation based on dichotomy is proposed. Firstly, the analytic design method of disc-shaped direct-acting roller cam is given according to the motion law of cam mechanism, and the coordinate determination formula of theoretical cam profile and actual machining cam outline is established. Then, the coordinates are determined by the coordinate measuring machine, and the mathematical model of processing error of each point in the cam contour is established. Finally, the mathematical model of machining error in MATLAB is realized, and a direct drive roller cam in the focusing mechanism of an aviation remote sensor is taken as an example to verify this new method. The experimental data shows that the maximum machining error of the cam profile points can satisfy the requirement of the focusing cam error well. Being simple and reliable, the algorithm can be used as an effective basis for judging whether disc-shaped direct-acting roller cams meet the requirements of error.

Attitude determination is essential for navigation of land vehicles, but the inertial sensors used for attitude estimation are susceptible to environmental disturbance. In this paper, vibrational influences on inertial sensors are analyzed. A method to use single-antenna GPS for pseudo-attitude estimation is presented. Then, an extended Kalman filter is proposed for data fusion. Results shown that the proposed method can determine attitude with vibration on land vehicles and estimate the acceleration well, compared with the complementary filters.
