    Protecting civil engineering structures from severe impacts like strong earthquakes has demanded intensive research in the past two decades. One of the most promising devices proposed for structural protection is the magnetorheological (MR) fluid dampers. To fully explore their potentials in the real-time feedback control implementations, accurate and robust modeling of the devices is a prerequisi... View full abstract»

    A new approach to the modeling and control of tokamak fusion reactors is presented. A nonlinear model is derived using the classical arguments of Hamiltonian mechanics and a low-order linear model is derived from it. The modeling process used here addresses flux and energy conservation issues explicitly and self-consistently. The model is of particular value, because it shows the relationship betw...

It is based on the use of a two-stage double-layered radial basis function (RBF) neural network. The first RBF stage is used to adaptively correct for the imperfections in the encoder signals such as me... View full abstract»

    This paper proposes a new approach to disturbance estimation based on a curvature model that improves the disturbance rejection performance of a servo system. The main feature is that the stability of the control system is guaranteed when the disturbance estimate is incorporated directly into the designed servo control law. Experimental results show that disturbances are rejected efficiently when ... View full abstract»

    Nonlinear system identification is considered using a generalized kernel regression model. Unlike the standard kernel model, which employs a fixed common variance for all the kernel regressors, each kernel regressor in the generalized kernel model has an individually tuned diagonal covariance matrix that is determined by maximizing the correlation between the training data and the regressor using ...

    This paper suggests a constrained H control scheme for active suspensions with output and control constraints. The H performance is used to measure ride comfort so that more general road disturbances can be considered. Time-domain constraints, representing requirements for: 1) good road holding which may have an impact on safety; 2) suspension stroke limitation;... View full abstract»

    A plant-wide oscillation in a chemical process often has an impact on product quality and running costs and there is, thus, a motivation for automated diagnosis of the source of such a disturbance. This brief describes a method of analyzing data from routine operation to locate the root cause oscillation in a dynamic system of interacting control loops and to distinguish it from propagated seconda...

    This brief uses an air conditioning system to illustrate the benefits of iteratively combining first principles and system identification techniques to develop control-oriented models of complex systems. A transcritical vapor compression system is initially modeled with first principles and then verified with experimental data. Both single-input-single-output (SISO) and multi-input-multi-output (M...

    Fault detection is critical in many applications, and analytical redundancy (AR) has been the key underlying tool for many approaches to fault detection. However, the conventional AR approach is formally limited to linear systems. In this brief, we exploit the structure of nonlinear geometric control theory to derive a new nonlinear analytical redundancy (NLAR) framework. The NLAR technique is app... View full abstract»

    This brief describes the implementation of a telemanipulation control architecture on a three degree-of-freedom (3-DOF) scaled master-slave telemanipulation system. Specifically, feedback linearization enables the use of loop-shaping compensators to increase the transparency bandwidth of a 3-DOF macro-micro telemanipulator pair, while the stability robustness of the system is maintained.

    This brief considers the state of charge (SOC) estimation problem for electrochemical batteries. Using an electric circuit model of the battery given in the literature, it is shown how the open-circuit voltage (which is directly related to the SOC) can be estimated based on the terminal voltage and current measurements provided there is sufficient variation in the battery current.

    A novel repetitive based-control strategy is proposed for the pulsewidth modulated (PWM) boost converter to compensate the output voltage ripple due to the harmonic distortion present in the input voltage. Repetitive control has shown to be a useful tool for tracking of periodic reference signals and for compensation of periodic disturbances, in other words, for harmonic compensation. The structur...
