Recently, cyber security becomes a serious problem for not only OA (Office Automation) systems but also PA (Process Automation) and FA (Factory Automation) systems. Even the controllers, which are not connected to Internet directly, have been attacked with malwares, such as Stuxnet and Quantum. When control system fails, it may lead to serious accidents such as explosion or leakage of poisonous and...
This paper reviews the integrated perturbation analysis - sequential quadratic programming (IPA-SQP) approach. The IPA-SQP approach has been proposed to address computational challenges in nonlinear model predictive control (MPC) problems. This approach combines the complementary features of perturbation analysis and sequential quadratic programming in a unified framework. An overview of the IPA-SQP...
In this paper, the challenging issue of estimating virtual unmodeled dynamics is addressed. A novel estimation algorithm based on historical data and the output of low-order approximation models for virtual un-modeled dynamics is presented. In particular, the virtual un-modeled dynamics are decomposed into known and unknown parts, where only the unknown part is to be estimated. The method effectively...
Web Services (WS), which are based on standard XML protocols, such as, WSDL, SOAP and UDDI, are the building blocks of Service Oriented Architecture (SOA). The aim of SOA is to automate web service tasks, such as, web service discovery, selection, composition and execution. Since XML is a syntax-based language, the automation of these tasks is still a challenge. To overcome this, web services can...
In this paper, we study how to build a front-end flow management system for SIP application servers. This is challenging because of some special characteristics of SIP and SIP applications. 1) SIP flows are well organized into sessions. The session structure should be respected when managing SIP flows. 2) SIP has been adopted by telecom industry, whose applications have more critical QoS requirements...
