Optimal Control for Electromagnetic Haptic Guidance Systems
summary
Real-time model predictive contour control guides a magnetized stylus by optimizing electromagnet position and current on a biaxial linear stage rather than forcing a moving setpoint, using a novel fast approximate electromagnet model to compute forces quickly. A prototype adds a permanent ring magnet to the pen and runs on off‑the‑shelf stages, evaluated with 12 participants and showing up to 2× accuracy on complex shapes while stage speed remains the main bottleneck.
