A nonlinear approach to flight path angle control is presented. Using backstepping, a globally stabilizing control law is derived. Although the nonlinear nature of the lift force is considered, theâ€¦ (More)

The robustness of non-linear regulators for nonlinear systems with respect to variations in gain is investigated. It is shown that there exist regulators that produce asymptotically stable closedâ€¦ (More)

This paper examines an index reduction method for linear time-invariant differential algebraic equations, with uncertainty in the equation coefficients. When the bottom block of a block upperâ€¦ (More)

It is shown that conditions that guarantee observability for continuous time nonlinear systems also imply observability for discrete measurements. This is used to show the existence of nonlinear deadâ€¦ (More)

Equations of motion of an axially symmetric sphere rolling and sliding on a plane are usually taken as model of the tippe top. We study these equations in the nonsliding regime both in the vectorâ€¦ (More)

Extentions of the RGA (relative gain array) technique to nonlinear systems are considered. The steady-state properties are given by an array of nonlinear functions. The high frequency properties areâ€¦ (More)

Although many of today's nonlinear control design algorithms assume the system dynamics to be affine in the control input, this often does not hold in practice. A remedy for this is to instead designâ€¦ (More)
