Canonical correlation analysis (CCA) has been used for concurrent quality and process monitoring to extract multidimensional correlation structure between process and quality variables. In this paper, a new kernel concurrent CCA (KCCCA) algorithm is proposed for quality-relevant nonlinear process monitoring, which decomposes the original space into five subspaces, including correlation subspace, quality-principal...
In this work, we present a novel RGB-D SLAM algorithm. The novelty of the proposed algorithm lies in the use of both feature points and plane patches for pose estimation. A plane patch is defined as a small-sized patch constructed by using a feature point with small curvature. The feature points with small curvature are called plane points. The remaining feature points are classified as either smooth...
Design space exploration (DSE) is now an important phase of the SoC design process, in order to realize high-efficiency design. In conventional DSE, design metrics such as speed, power and area are extensively used to evaluate various design options. As IP-reuse is widely adopted, protection of hardware IPs has been paid more and more attention at advanced design processes. This paper considers IP...
Nonlinear robust tracking of the flight-path angle in the longitudinal channel of aircraft is a challenging control problem. The main difficulty results from its non-minimum phase characteristics and the unavoidable uncertainty and disturbances existing in the internal dynamics. To solve the problem, this paper presents a nonlinear control scheme based on an Uncertainty and Disturbance Estimator (UDE)...
A structure singular value (SSV) μ synthesis control strategy based on D-K iteration method was proposed to conquer unstructured and structured perturbations for a proton exchange membrane fuel cell (PEMFC) generation system. The D-K iteration method was utilized to solve the proposed controller by combining a standard H∞ optimization problem and a convex optimization problem at each frequency. The...
High performance XY-table is commonly incorporated into IC manufacturing and packaging equipments. In order to achieve higher acceleration, a novel XY positioning table synchronously driven by one-side dual linear motors is proposed. The redundant drive system commonly suffers from synchronous drive precision problem at high speed and acceleration rates. In this paper, the dynamic model of dual linear...
This paper presents a robust H?? full-state feedback control synthesis method for uncertain systems with D11 ?? 0. The method is applied to the robust stabilization problem of the Space Station in the face of inertia matrix uncertainty. The control design objective is to find a robust controller that yields the largest stable hypercube in uncertain parameter space, while satisfying the nominal performance...
