The presence of two actuators and nonlinear behavior of the system makes the problem difficult to handle using classical control designs. Instead, we employ a recently developed control Lyapunov function based design method that guarantees a robustness property interpretable as gain and phase margins. The controller has been tested in simulations and experimentally in the dynamometer test cell.","PeriodicalId":364267,"journal":{"name":"Proceedings of the 1998 American Control Conference.

First, we derive a sufficient condition for the dynamical system to have μ less than a specified value γ by using parameter-dependent multipliers and the positive real lemma. It requires no higher order multiplier and no frequency sweep while being less conservative than former methods. Second, based on this result, we give an LMI condition for the existence of a state feedback gain which achieves that μ of the closed loop system is less than given γ. Finally, an illustrative numerical example is given.","PeriodicalId":364267,"journal":{"name":"Proceedings of the 1998 American Control Conference. ACC (IEEE Cat.

The technique uses multivariate orthogonal modeling functions generated from the data to determine nonlinear model structure, then expands each retained modeling function into an ordinary multivariate polynomial. The final model form is a finite multivariate power series expansion for the dependent variable in terms of the independent variables. Partial derivatives of the identified models can be used to assemble globally valid linear parameter varying models. The technique is demonstrated by identifying global nonlinear parametric models for nondimensional aerodynamic force and moment coefficients from a subsonic wind tunnel database for the F-16 fighter aircraft. Results show less than 10% difference between wind tunnel aerodynamic data and the nonlinear parameterized model for a simulated doublet maneuver at moderate angle of attack. Analysis indicated that the global nonlinear parametric models adequately captured the multivariate nonlinear aerodynamic functional dependence.","PeriodicalId":364267,"journal":{"name":"Proceedings of the 1998 American Control Conference.

In the proposed problem formulation, the unknown plant is assumed to belong to one of N possible uncertainty models, where each model is described by a known, linear nominal plant with H/sub /spl infin// bounds on the unmodeled dynamics. We show that if each of the models can be robustly stabilized with a linear time-invariant (LTI) controller, then there exists a single adaptive (possibly nonlinear and time-varying) controller that simultaneously robustly stabilizes all the N possible uncertainty models. The adaptive controller can provide the same level of stability robustness as the LTI controllers, and introduces, at most, a bounded transient in the output. Our approach is based on a simple switching algorithm and a novel application of H/sub /spl infin// filtering methods.","PeriodicalId":364267,"journal":{"name":"Proceedings of the 1998 American Control Conference.
