“…In general, the state-space representation is a mathematical tool used for modeling a state-determined system's outputs for varying inputs u 1 (t), u 2 (t),..., u n (t), state-variables x 1 (t), x 2 (t),..., x n (t) and output variables y 1 (t), y 2 (t),..., y n (t). It is commonly used for modeling the behavior of linear time-invariant (LTI) systems, as shown in Figure 6, taken from [36]. Rowell defines a state-determined system, in [37], as follows: "if a system is statedetermined, knowledge of its state-variables x 1 (t), x 2 (t),..., x n (t) = x(t) at some initial time t 0 and inputs u 1 (t), u 2 (t),..., u n (t) = u(t) for t > t 0 is sufficient to determine all future behavior of the system".…”
