It has been found that some huge overshoot in the sense of sup-norm may be observed when typical iterative learning control (ILC) algorithms are applied to LTI systems, even though monotone convergence in the sense of λ-norm is guaranteed. In this paper, a new ILC algorithm with adjustment of learning interval is proposed to resolve such an undesirable phenomenon, and it is shown that the output error can be monotonically converged to zero in the sense of sup-norm when the proposed ILC algorithm is applied. A numerical example is given to show the effectiveness of the proposed algorithm.

In this paper, we extend the observer/control strategies previously published in [25] to an n -link, serially connected, direct drive, rigid link, revolute robot operating in the presence of nonlinear friction effects modeled by the Lu-Gre model. In addition, we also present a new adaptive control technique for compensating for the nonlinear parameterizable Stribeck effects. Specifically, an adaptive observer/controller scheme is developed which contains a feedforward approximation of the Stribeck effects. This feedforward approximation is used in a composite controller/observer strategy which forces the average square integral of the position tracking error to an arbitrarily small value. Experimental results are included to illustrate the performance of the proposed controllers.

This paper is concerned with the design of Multi-Inputs and Multi-Outputs (MIMO) predictive PID controllers, which have similar performance to that obtainable from model-based predictive controllers. A new PID control structure is defined which incorporates the prediction of future outputs and uses future set point. A method is proposed to calculate the optimal values of the PID gains from generalised predictive control results. A decentralized version of the predictive PID controllers is presented and the stability of the closed loop system is studied. Simulation studies demonstrate the superior performance of the proposed controller compared with a conventional PID controller. The results are also compared with generalised predictive control solutions.

Mississippi State University students in their third year of Challenge X competition have transformed a 2005 Chevrolet Equinox into a diesel-electric hybrid at a 99% buy-off vehicle readiness level. The vehicle, configured in a charge sustaining, through-the-road parallel architecture, offers significant improvements over the stock vehicle with a 45% increase in fuel economy and a 3.5% increase in 0-60 mph acceleration, while maintaining a Tier 2 Bin 8 EPA emissions rating with an impressive towing capacity of 2500 lbs. The MSU Equinox utilizes a 1.9 L diesel engine burning B20 biodiesel fuel with a six-speed manual transmission that is augmented by an ac induction electric motor-transaxle assembly. A nickel metal hydride (NiMH) battery pack provides sufficient energy storage to accomplish peak shaving so that the engine operates in its most efficient regime. Optimal vehicle performance was achieved with the powertrain system analysis toolkit (PSATtrade) and MATLABtrade that facilitated the design of an advanced vehicle architecture and control strategy to reduce energy consumption and emissions. Simulation results are compared with actual experimental data obtained on a four-wheel chassis dynamometer and road tests so as to validate the mathematical model. These studies together with several documented vehicle improvements bring the MSU Equinox to a 99% buy-off readiness level so as to comply with competition requirements.

In this paper we propose a multiple auction-based task allocation scheme for identifying and distributing network-monitoring and decision-making tasks amongst the various nodes in a wireless ad-hoc network for performing power-aware intrusion detection. By iteratively performing this scheme we show that a power-optimal solution can be reached in a bandwidth constrained and energy-preserving network with only the nodes capable of supporting the various tasks chosen. We also demonstrate that simultaneous localized auctions have a lesser overhead than a single auction based scheme that was a subject of our previous work. Our scheme also serves to distribute the intrusion detection tasks according to the needs and constraints of a large and dynamic network. We have compared the performance of our scheme with the existing power-aware intrusion detection approaches in terms of various performance metrics and have demonstrated its associated low overhead

A nonlinear adaptive-robust scheme is presented to control a class of nonlinear systems. It effectively combines the design techniques of adaptive and robust control to improve performance by retaining the advantages of both techniques. It enhances transient performance and eliminates robustness problems compared to a parameter adaptive control. It also improves tracking performance by reducing modeling uncertainty and optimizes control effort by estimating bound uncertainty compared to a deterministic robust control. The controller is applied to a spacecraft making the body frame track a reference orientation, when there are parametric uncertainty, modeling errors, and external disturbances

One of the key design issues for the next generation routers is the IP Lookup mechanism. IP address lookup is the challenging because it requires a longest matching prefix lookup. It is compounded by increasing routing table size, increased traffic and migration to IPv6 addresses. Existing solutions like BSD radix Tries, scale poorly when traffic in router increases or when employed for the IPv6 addresses. In our paper we describe a parallel computation models based lookup for the routing table. This mechanism provides lookup for a maximum of n*16 IPv6 addresses simultaneously, where n represents the number of processors. We propose a parallel binary trie search technique for the lookup to facilitate concurrent insertions and searching on the routing table. Using the proposed technique a router can achieve a much higher packet forwarding rate and throughput.
