DIRECTSD 3.0 toolbox for MATLAB: Further progress in polynomial design of sampled-data systems

The paper presents a new version of the DirectSD toolbox for optimal design of sampled-data systems in Matlab. This software realizes recently developed polynomial methods for optimal sampled-data systems design on the basis of parametric transfer function theory. As distinct from previous versions, the macros are applicable to the standard structure of sampled-data system with SISO controller
