A new avenue of research in robust and ultrafast decentralized control

A new control algorithm that guarantees ultrafast and robust control for unstable invertible plants (Bensoussan, 2014) has been recently tested at McGill University (Bensoussan, 2015, Bensoussan & Boulet 2015). It has shown that it is possible to get a time response with minimal overshoot and with settling time equal to rise time while keeping good stability margins. This method can be extended to multivariable unstable invertible systems that are ultimately (i.e. at high frequency) diagonally dominant, ensuring decentralized control while using local (i.e. diagonal) controllers.
