Linear controllability by piecewise constant controls with assigned switching times
For a linear time-dependent control process in \(R^ n\), we prove that the complete controllability by means of the space of all the admissible controls is equivalent to the complete controllability by means of a suitable n-dimensional space of piecewise constant controls with at most n preassigned switching times. An analogous result is also established for more general controllability problems.
