Further Remarks on the Controllability of Linear Constant Delay-Differential Systems

摘要

Function space null controllability is considered for certain delay differential systems. The implications of the input decoupling factors and input decoupling zeros of the corresponding system matrices are examined. Results demonstrate that a transformation of system similarity over the defined function space between the discussed system matrices will preserve the function space null controllability. It does not follow that system matrices which correspond to function space null controllable systems (and have no output decoupling factor) are system similar over the defined function space if they correspond to the same transfer function matrix.
