Robust Control Design for Suppressing Random Exogenous Disturbances in Parametrically Uncertain Linear Systems

The design problems of robust static controllers for discrete-time systems with norm-bounded parametric uncertainties and random input disturbances are considered. The controllers under consideration stabilize the plant for all possible values of uncertainty from a given set of parameters and also guarantee a desired suppression level for random exogenous disturbances. A numerical example is given.

Robust static control algorithm for linear objects

We propose a robust static control algorithm for linear objects under parametric and structural uncertainty and an external uncontrollable disturbance. The resulting algorithm ensures that the object output tracks the reference signal with the necessary precision. We give modeling results that illustrate that the algorithm operates correctly.

CONTROL OF MARS GUIDED ENTRY (PART II): ROBUST NONLINEAR DYNAMICS INVERSION

This paper addresses the 6 degrees-of-freedom control of a Mars Lander Module during its aerodynamic entry phase. It focuses on Robust Nonlinear Dynamics Inversion (RDI) technique. On one hand, RDI is shown to be efficient for translation controller synthesis. On the other hand, this technique is shown to be inappropriate for attitude control except for the gyroscopic torque cancellation which could be coupled with a robust static controller. Monte-Carlo simulations are performed to demonstrate the robust performance of the 6 DOF control software. The nonlinear simulator includes a realistic model of the atmosphere (European Mars Climate Database) and Mars gravity (J2).
