Optimal stimulation to keep the velocity constant during stimulation. Field strengths are solutions are solutions to the problem in Eq. (33) with maximum field strength defined as in Eq. (36). Left: bulk velocity using different maximum electric field strengths (see legend). Middle: physical electric field profile showing similar stimulation protocols. Right: terminal velocity error decreases when the maximum normalized electric field strength increases. Parameter values correspond to the posterior means for $\alpha$, ${\tau }_a$, ${\tau }_e$, and the pre-computed value for $\gamma$ (color figure online)
