<p>We investigate the time complexity of constructing single input<br />double output state feedback controller structures, given the <br />directed structure graph G of a system. Such a controller structure<br />defines a restricted type of P3-partition of the graph G. A necessary<br /> condition (*) has been found and two classes of graphs have<br />been identified where the search problem of finding a feasible P3-<br />partition is polynomially solvable and, in addition, (*) is not only<brdoi:10.7146/brics.v8i18.20475 fatcat:vvjvh4b7t5aizhrc7ualm7q36q
