An Integrated Software Environment For Powertrain Feasibility Assessment Using Optimization And Optimal control

Asian Journal of control 2008年第3期8卷

作者： Ilya V. Kolmanovsky Jing Sun Shiva N. Sivashankar During the summer of 1993 he was a visiting scholar in the Department of Aeronautics and Astronautics Naval Postgraduate School Monterey CA where he worked on control systems for unmanned aerial vehicles. From 1993 to 2000 he was with Ford Research Laboratory working on several design aspects of powertrain control systems and processes for embedded control software development. He is currently the Vice President for Technology at Emmeskay Incorporated a company that provides systems engineering based products and services. His research interests include modeling and control of automotive systems application of systems engineering methods and tools to product development processes and multivariable robust control and estimation methods. Dr. Sivashankar has served as an associate editor for the ASME Journal of Dynamic Systems Measurement and Control.

With the increase in automotive powertrain complexity, an upfront assessment of powertrain capability in meeting its design targets is important early on in the development programs. The optimization of control policy based on powertrain simulation models can facilitate this assessment and establish limits of achievable performance for a given powertrain configuration and parameters. The paper discusses several computational optimization and user interface solutions for deploying a numerical optimal control approach in a user-friendly software environment.

Fermentation process possesses high non-linear and time difference, and its inherent mechanism is very complex. To carry out further optimizing and control strategy, reasonable model must be gained. There are many critical variables, which are hard to gain in fermentation process. It hold back the effective application of optimal and strategy procedure. Least square support vector machine (LS-SVM) is a kind of extension of support vector machine (SVM). The algorithm of LS-SVM has high precision, fast computing. It is more suitable for predicting online. LS-SVM is presented for modeling of penicillin fermentation process. A model is built by LS-SVM with RBF kernel for mycelial and penicillin. The research result indicates that LS-SVM is an effective method for penicillin ferment process modeling.

Increasing demand for improved reliability and survivability of mission-critical systems is driving the development of health monitoring and Automated Contingency Management (ACM) systems. An ACM system is expected to adapt autonomously to fault conditions with the goal of still achieving mission objectives by allowing some degradation in system performance within permissible limits. ACM performance depends on supporting technologies like sensors and anomaly detection, diagnostic/prognostic and reasoning algorithms. This paper presents the development of a generic prototype test bench software framework for developing and validating ACM systems for advanced propulsion systems called the Propulsion ACM (PACM) Test Bench. The architecture has been implemented for a Monopropellant Propulsion System (MPS) to demonstrate the validity of the approach. A Simulink model of the MPS has been developed along with a fault injection module. It has been shown that the ACM system is capable of mitigating the failures by searching for an optimal strategy. Furthermore, few relevant experiments have been presented to show proof of concepts. © 2007 EUCA.

Partner selection is a key problem of organizing a virtual enterprise. A multi-objective optimization model, which analyzes these candidate enterprises quantitatively is proposed and accomplished by an improved genetic algorithm. This algorithm sorts several single object fitness using quick-sorting algorithm and selects based on total fitness, crossovers and mutates using the self-adaptive probability, and finds the global optimal solution at last. Through comparison with standard GA and the improved self-adaptive GA, simulation example testifies the latter efficiency.

Concurrent Modified Square Contour Algorithm and Soft Decision-Directed Scheme for Blind Equalization

International Conference on Fuzzy Systems and Knowledge Discovery (FSKD)

A new blind equalization scheme is proposed based on concurrent modified square contour algorithm (MSCA) and a novel soft decision-directed (SDD) adaptation. This proposed blind equalization scheme (MSCA+SDD) may be viewed as operating a MSCA equalizer and a SDD equalizer concurrently. The MSCA term provides good steady- state equalization performance and global convergence, moving the equalizer weight vector on the correct direction; after the equalizer enters the fine local convergence region, the SDD term helps to accelerate convergence. The performance is measured for realistic microwave channel models and the simulation results demonstrate that both the MSCA+SDD and the MSCA have the same steady-state equalization performance, but the former has a faster convergence speed.

For quaternion model of two-dimensional harmonics, the singular values decomposition (SVD) method of quaternion matrix presented to estimate frequency pairs of two- dimensional harmonics. This method may estimate the number of signals by singular values. The left and right singular vectors of quaternion matrix were used to estimate frequency pairs. This method needs lesser data and data matrix is very simple. Simulations show that this method can decrease computation burden effectively than other methods.

A dynamic scheduling strategy based on network running situation is proposed to allocate network bandwidth by adjusting the sample periods of control systems sharing CAN resource in the networked control systems. Then the NCS is a vary-sample period system which is modeled as a class of discrete switched systems when network-induced delay and data-packet dropout exist. Based on the model, the approach of robust controller design is studied. Finally, a group of simulations validate the effectiveness of the control and scheduling co-design method.

This paper considers the general filtering problem for a distinct class of two-dimensional (2-D) discrete linear systems, i.e. information propagation in two independent directions, known as discrete linear repetitive processes which are of both system-theoretic and applications interest. In particular, new results on the design of filters with guaranteed levels of performance are developed. These take the form of algorithms for the design of an ∞ and 2-∞ dynamic output feedback filter which guarantees that the resulting filtering error process is stable and has prescribed disturbance attenuation performance as measured by ∞ and 2- ∞ norms. © 2007 IEEE.
