This work studies the Lorentz force‐based polymer hard‐magnetic micromirror for optical switch application. For this purpose, a robust control design is proposed, which is based on the linear quadratic gaussian method incorporating with the well‐known internal model principle. The proposed scheme can simultaneously be easily implemented and it can improve the positioning performances and noise rejection ability. The effectiveness is verified by experimental results.
