Welcome to the World of Robust Control Systems
Controlling Uncertain Systems with Certainty
The presence of uncertainty affects the stability and performance of a control system. To mitigate the negative impact of uncertainty, control systems have to be designed to accommodate the uncertainty right at the design stage. That is where Robust Control Systems play a big role.
Transformation Allergic Approach
Our firm Robust Engineering Systems, LLC developed a software named RES CSSP Tool-Box
(Robust Engineering Systems Control Systems Design Toolbox)
RES CSSP ToolBox contains highly innovative, breakthrough type, new control systems design techniques not available in the current literature software Control Systems Design Tool-Box
RES CSSP Tool-Box contains novel, new methods of control systems design that can even stabilize many current literature control problems discarded by current literature software control systems design tool-box techniques as being difficult to stabilize and control.
RES CSSP Tool-Box contains new control systems design methods that accommodate uncertainty in the form of real parameter variations, unmodeled dynamics, multiple equilibrium points, and errors in guidance commands and in the initial conditions and even few time varying perturbations.
Current Literature
The current literature software based control systems designs are limited in their scope and are constrained by the obligation to connect time domain, state space systems with frequency domain, transfer function control theory. These designs aiming for negative real part eigenvalues as the stability criterion are highly non-robust having Zero Real Stability Margins.

Applications
Dynamics & Control
Aircraft
Current literature Aircraft Dynamics Models in the open loop situation are categorized as having Phugoid and Short-Period Modes and are designed for closed loop stability separating the dynamics under `fast dynamics (short period)' and `slow dynamics (phugoid)' type time scale separation viewpoint which introduces non-robustness. Our RES CSSP Tool-Box designs do not need such assumptions. They promise very high robust stability margins for various types of perturbations.
