The Complex-Step Derivative Approximation on Matrix Lie Groups
Charles Champagne Cossette, Alex Walsh, James Richard Forbes
The complex-step derivative approximation is a numerical differentiation technique that can achieve analytical accuracy, to machine precision, with a single function evaluation. In…
Invariant Extended Kalman Filtering Using Two Position Receivers for Extended Pose Estimation
Natalia Pavlasek, Alex Walsh, James Richard Forbes
This paper considers the use of two position receivers and an inertial measurement unit (IMU) to estimate the position, velocity, and attitude of a rigid body, collectively called…
Interior-Conic Polytopic Systems Analysis and Control
Alex Walsh, James Richard Forbes
Linear parameter varying (LPV) analysis and controller synthesis theory rooted in the small gain and passivity framework currently exist. The study of conic systems encompasses bot…
