This paper aims to analyze the stability of a special class of single-channel slow-rotating homing missiles using the Frank–Wall stability criterion. To achieve this, starting from the model of a slow-rolling missile with six degrees of freedom (6

Following the completion of the installation and testing of the HPLS 2x10PW laser system at ELI-NP, prospective experiments related to spectral broadening in thin films for post-compression were performed at the HPLS 100TW output.

We have shown, for the first time in the world, the production of 10 PW peak power laser pulses and their propagation to an experimental area at the Extreme Light Infrastructure - Nuclear Physics (ELI-NP). We are also steadily running the laser syste

Inverting a state-space system A,B,C,D is a problem implying that the transmission zeros, of the system we want to invert, lie in the open left half plane. This is solved by finding an appropriate D matrix. We will show that finding D turns into a st

The L1 Adaptive control technique is applied to the F-18 HARV (High Alpha Research Vehicle) aircraft. This control architecture compensates for both the matched and the unmatched uncertainties of the full nonlinear aircraft dynamics. This paper descr

The paper presents a Kalman filtering problem for discrete–time linear systems with parametric uncertainties. A stochastic model with multiplicative noise both in the state and in the output equations is used to represent the system with uncertain

An L 1 adaptive controller is proposed to control the short period dynamics of the F-18 HARV experimental aircraft when affected by bounded uncertainties, bounded external disturbance and time delay. The reference model is improved with a linear quad
