#### Pitch and flight path control with simultaneous forward gust rejection

(1999)

The problem of rejecting atmospheric disturbances with simultaneous input-output decoupling of the pitch angle and the flight path angle of an aircraft, is studied. The problem is proven to be solvable for almost all flight ...

#### Characterization of the allowable perturbations for disturbance rejection and data sensitivity

(1996)

In this paper the problem of disturbance rejection and data sensitivity is studied for the case of linear time invariant systems. Using a proportional state feedback law, the necessary and sufficient conditions for the ...

#### Robust discretization algorithms for the numerical intergration of nonlinear PDEs with application to a generalized capacitor

(1998)

Numerical integration of nonlinear (NL) partial differential equations (PDEs) is studied via approximating the original continuous-domain physical system by a discrete multidimensional (MD) and passive system, using ...

#### Controller design for lateral manoeuvres in electromagnetic wind tunnels

(1996)

The roll angle, the yaw angle and the side-slip position of test aircrafts in electromagnetic wind tunnels, are independently controlled. The problem is proven to be always solvable by applying a static state feedback law ...

#### P-D feedback for decoupling and pole assignment of singular systems

(1998)

The problem of reducing a multi input-multi output system to many single input-single output systems, namely the problem of input-output decoupling, is studied for the case of singular systems i.e., for systems described ...

#### Rotary gust rejection for helicopters

(1998)

For the case of helicopters in straight horizontal flight, the effects of a rotary gust to the forward velocity and the downward velocity of the helicopter are rejected. The rotor commands appear to be independent, i.e. ...

#### Noninteracting control for helicopter in straight horizontal flight

(1998)

Pitch angle and forward velocity are decoupled via a static state feedback law for the case of helicopter in straight horizontal flight. The set of stability derivatives for which decoupling is satisfied, is explicitly ...

#### Position control for constrained Robots

(1999)

The problem of position control, for robot manipulators constrained to carry a load, is studied. Using a nonlinear P-D feedback law the design requirements of command matching and command following are proved to be always ...

#### Generalized Hankel matrix for the minimal realization of singular systems

(1996)

A generalized Hankel matrix (in pencil form) is introduced. Based upon this definition the dimension of the minimal realization and the controllability and observability properties are related in a straight forward way. ...
