A new control method [1] of unstable and invertible plants has been shown to be outperforming regular H2 , H and μ-synthesis controllers. It has been applied to a levitation system [2] and to the control of a drone. Simulation has also been done on a satellite antenna controller with satisfying results.

This sensitivity-based design method has been extended to multivariable unstable and invertible plants which are ultimately (i.e. at high frequencies) diagonally dominant and achieves decentralized control.

Simple interactive design methods have been developed on the GeoGebra platform so as to achieve superior performance in the time domain and in the frequency domain.

This new control method has been extended the field of Adaptive control. We will focus on the L1 Adaptive method and propose alternative architectures which improve time and frequency performances, including the attenuation of both input plant perturbation and output additive external disturbances.
