“…Therefore, system (2) is controllable on ðϑ l , t l + 1 T . Since, l 2 {1, 2, … , p} is arbitrary, hence from Equations (10) and (11), one can conclude that for i = 1,2,…, p , system is controllable on ½0, t 1 T and ðϑ i , t i + 1 T . Thus, from Definition III.2, system (2) is totally controllable on I.…”
