Adaptive control of a class of slowly time varying systems with modeling uncertainties
(2005)In a recent work, a new linear adaptive controller based on certaintyequivalence and backstepping design, which promises a level of transient and asymptotic performance comparable to that of the tuning functions adaptive ...

Adaptive LQ control with antiwindup augmentation to optimize UAV performance in autonomous soaring applications
(2008)The performance of a glider can be considerably improved by means of soaring and optimization of its trajectory. Recent advances in the area of static soaring assume known linear glider dynamics and no actuator saturation ...

Aliasing probability calculations in nonlinear compactors
(2003)This paper discusses a systematic methodology for calculating the aliasing probability when an arbitrary finitestate machine is used to compact the response of a combinational circuit to a sequence of randomly generated ...

Application of three bivariate timevarying volatility models
(2001)The multivariate timevarying volatility models have recently attracted a lot of attention in the statistics/econometrics community. We apply two bivariate ARCHGARCH models and a bivariate unobserved ARCH model to a series ...

Backstepping Control of Linear TimeVarying Systems with Known and Unknown Parameters
(2003)The backstepping control design procedure has been used to develop stabilizing controllers for time invariant plants that are linear or belong to some class of nonlinear systems. The use of such a procedure to design ...

Bounds on FSM switching activity
(2008)This paper obtains lower and upper bounds for the switching activity on the state lines of a finite state machine (FSM) that is driven by typical input sequences. More specifically, the paper provides bounds on the average ...
