Robust multivariable control systems can improve the performance of electric generating plants. This paper presents results on the applicability of a particular methodology for the design of such control systems to an electric generating plant. A simulation of the Philadelphia Electric Company Cromby No.2 unit is used as the test-bed. Experimental designs demonstrate the tradeoff between performance...
Flutter phenomena associated with various store loadings on modern fighter aircraft wings are diverse and can severely inhibit performance. Passive means of suppressing flutter can be costly in terms of performance as well. Active flutter suppression is a potential means for overcoming these performance degradations. Adaptation is required to treat the diverse flutter phenomena. This application is...
This paper considers the problem arising from the design of an autopilot for a large booster. The motion-controlling actuators of the booster have both position and rate limits. The problem is formulated as a bounded phase-coordinate problem and analyzed by the "backing out of the target" procedure. A method of constructing the optimal control is presented. An example of an oscillatory system...
