Tropical cyclone (TC) translation speed often affects the time of strong wind attacks and precipitation accumulation in areas that TCs pass through. Therefore, trend TC has important implications for TC-related risks current future climate. In this paper, trends over Western North Pacific (WNP) from 1980 to 2018 are analyzed, lifetime maximum intensity (LMI) is proposed as a factor related inte...

model order reduction is known as the problem of minimizing the -norm of the difference between the transfer function of the original system and the reduced one. in many papers, linear matrix inequality (lmi) approach is utilized to address the minimization problem. this paper deals with defining an extra matrix inequality constraint to guarantee that the minimum phase characteristic of the sys...

this paper presents a new observer design methodology for a time varying actuator fault estimation. a new linear matrix inequality (lmi) design algorithm is developed to tackle the limitations (e.g. equality constraint and robustness problems) of the well known so called fast adaptive fault estimation observer (fafe). the fafe is capable of estimating a wide range of time-varying actuator fault...

Centralized nonlinear fusion filter design problem is to construct an asymptotically stable observer that leads to a stable estimation error process whose L2 gain with respect to disturbance signal is less than a prescribed level for state estimation of the multi-sensor fusion system. This paper tries to resolve the problem in using of H∞ filtering theory and LMI methods under certain condition...

Abstract. An elimination problem in semidefinite programming is solved by means of tensor algebra. It concerns families of matrix cube problems whose constraints are the minimum and maximum eigenvalue function on an affine space of symmetric matrices. An LMI representation is given for the convex set of all feasible instances, and its boundary is studied from the perspective of algebraic geomet...

The paper is dedicated to experimenting a simple LMI procedure to design simple adaptive control laws for ’almost stable’ systems. The procedure initially conceived for regulation problems around zero equilibrium point is extended to PID like tracking control problem. LMI results gives conditions to guarantee robustness of the simple adaptive control law with respect to parametric uncertainties...

This paper presents a convex optimization method for the feedback-loop tradeoff of L1 adaptive controller. Both problems of performance improvement and time-delay margin maximization are shown to be cast into Linear Matrix Inequality (LMI) type conditions. First, each of these conditions is studied separately towards a distinct objective, and next two similar LMI algorithms are proposed for opt...

Necessary and sufficient conditions are formulated for checking robust stability of an uncertain polynomial matrix. Various stability regions and uncertainty models are handled in a unified way. The conditions, stemming from a general optimization methodology similar to the one used in /i-analysis, are expressed as a rank-one LMI, a non-convex problem frequently arising in robust control. Conve...

Based on kinematic and kinetic analyses of the 3-Degree of Freedom differentially driven wheels mobile robot, we proposed a nonlinear mathematical model with uncertain disturbance. This model was transformed into linear control systems through an approximate linearization algorithm, which is based on balanced flow pattern. After that, we designed a partial feedback H∞ robust controller based on...
