The Robust-Control Toolboz  is a collection of 40 "M-files" which extend the capability of PC/PRO-MATLAB to do modern multivariable robust control system design. Included are robust analysis tools like singular values and structured singular values, robust synthesis tools like continuous/discrete H2/H o° synthesis and LQG Loop Transfer Recovery methods… (More)
The recently developed nonlinear servomechanism theory is applied to the attitude control of large maneuvering spacecraft subject to sinusoidal disturbances and parametric uncertainties. Simulation shows signticant advantages of our attitude controller over the controller resulting from the feedback linearization approach.
q’his paper presents a systematic method to design roljust colitrollem from experimental data so as to ensure that the cont,rollcr is robust with J espect to all plants which cannot be discounted based on the data (to within a specified statistical confidence). l’hc present paper extends previous multi variable results to the structured uncertainty case and… (More)
This paper designs a fuzzy logic controller to suppress the vibrations of a large space antenna-like ground experimental structure located at the JPL/AFPL Large Spacecraft Control Laboratory. This fuzzy logic controller provides a simple, yet robust, means to the vibration control of a highly uncertain structural system.
