Yes. Reformulate the systems transfer function into a state space representation, and then solve the algebraic ricatti equation to find an optimal gain matrix. This is know and the LQR problem.

Switching the output from 100% to -100% is another viable approach, known as bang-bang control, but it is not necessarily optimal
