 Homogeneous Systems Control Toolbox (HCS Toolbox) for MATLAB is a collection of functions  for design  
 and tuning of control systems with improved control quality (faster convergences, better robustness, 
 smaller overshoots, etc) based on the concept of a dilation symmetry (homogeneity).

+Homogeneous controllers/observers design as well as procedures for upgrading of existing linear 
 controllers/observers to nonlinear (homogeneous) ones are developed for both 
 Single-Input Single-Output (SISO) and  Multiply-Input Multiply-Output (MIMO) systems.
