We introduce an optimization-based open-loop control method for 2D wavefront modulators. The optimization problem is convex with inequality constraints and can be solved using an interior-point method in real-time. Compared to conventional influence matrix inversion, this new method takes into account the system limitations, such as the actuation polarity and voltage limits of the drivers. It searches for the global optimum of actuation signals within system boundary constraints. Consequently, while reducing the complexity of the hardware, it is more immune to systematic errors and guarantees optimality of the actuation signals. The control system is implemented on two different electrostatically-actuated phase modulators; a conventional deformable mirror and a novel refractive optofluidic phase modulator. We experimentally compare the performance of the optimizationbased controller with conventional methods for high order Zernike mode replication. It is demonstrated that the introduced technique enables more accurate control for both modulators, particularly at large correction amplitude and/or higher order corrections.
