The recently proposed integrated direct/indirect adaptive robust controller (DIARC) for a class of nonlinear systems with unknown input dead-zones is combined with desired trajectory compensation to achieve asymptotic stability with excellent tracking performance. The algorithm is tested on a linear motor drive system preceded by a simulated non-symmetric dead-zone which is practically supposed to...
Recommendation-based trust models have emerged as an important risk management mechanism in E-commerce and online environments. This paper presents a trust model with recommendations management based on subjective logic and Bayesian estimation. For dealing with recommendations, the theory of subjective logic is used to express trust properties as beliefs and a method is provided for mapping between...
Tracking reentry vehicle with strong maneuvers on-line is a challenging task. The key is to develop suitable dynamic models and estimation methods. Two kinds of modeling methods are discussed for reentry tracking, and the unscented filter (UKF) is introduced to the nonlinear tracking system. To reduce the computational load, three simplifications of UKF are developed. Furthermore, the feasibility...
