Unlike the results of Figure 4 where only linear, time-varying control designs utotal*=a^t+b^ were used, in Figure 5 nonlinear designs for real-time optimal control utotal*=a^t+b^+ω¯×J¯¯ω¯ (with and without switching) were used. Notice the open-loop optimal control is visually indistinguishable from nonlinear, time-varying control designs in the graphic depiction.
