    This article addresses thermal feedback control of distributed-parameter, dynamic nonlinear heat transfer phenomena involved in rapid prototyping processes. These mechanisms are captured in a numerical simulation of the thermal field generated during such operations. For the design of a multivariable controller, a linearized state-space model of lumped temperatures and heat inputs on a grid is est... View full abstract»

    The Stanford's Quiet Hydraulic precision lathe was designed to use an exclusively hydraulic approach and equipped with an open liquid circulation system. By using a temperature-controlled liquid for a liquid shower, as well as for machine actuation, a uniform temperature environment can easily be maintained and the machining accuracy level can be assured. The liquid temperature is regulated by a c... View full abstract»

    This article presents experimental results of a transonic wind-tunnel test that demonstrates the use of generalized predictive control for flutter suppression for a subsonic wind-tunnel wing model. The generalized predictive control algorithm is based on the minimization of a suitable cost function over finite costing and control horizons. The cost function minimizes not only the sum of the mean s... View full abstract»

    Flotation processes are important in the mining industries and because of their multivariable nature, require a more advanced approach for the control systems. The level control used in the flotation process is not a trivial problem and needs to be addressed so as to optimize the entire multivariable system. Windows NTTM Workstation is becoming a more prevalent choice of a robust operat... View full abstract»

    This article describes the development and application of a multivariable neural controller for automatic ship berthing. Following a brief review of various methods employed in automatic ship control, an online trained, backpropagation-based neural network controller is presented. The principal intention is to take advantage of the learning ability of neural networks, and to derive an autonomous n... View full abstract»

    A real-time fault detection algorithm for the Space Shuttle main engine (SSME) is presented in this article. The system for anomaly and failure detection (SAFD) has been successfully tested on the NASA Technology Test Bed (TTB)engine at Marshall Space Flight Center in Alabama. It is currently being tested on the NASA Stennis test stand A-1, and has already proved its capability by detecting a fail... View full abstract»

    A friction estimation and compensation technique was implemented on a laboratory apparatus designed to permit the direct measurement of friction. Experimental results are reported for a friction observer which estimates total friction present assuming it to be a constant times the sign of velocity. A second observer is used to estimate the velocity using the measured position of the rotating shaft... View full abstract»

    A simplified scheme for scheduling multivariable controllers for robust performance over a wide range of plant operating points is presented. The approach consists of scheduling only the output matrix of a dynamic controller, thus significantly reducing the number of parameters to be scheduled. The approach starts with a given robust controller at a nominal design point designed such that it gives... View full abstract»
