Response surface methodology (RSM), the targeted action, quadraticpolynomial, wiper
Overtravel in windshield wipers can cause noise and product damage. While feedforward control leverages dynamic characteristics to mitigate this issue, pinpointing the overtravel cause is challenging compared to flutter. Vehicle structural rigidity also complicates accurate modelling. Conversely, PI controllers offer simpler implementation without detailed models but face practical sensor cost constraints. This paper proposes reducing feedforward control by adjusting target actions. It addresses target action representation and optimal exploration, using sinusoidal waves to adjust peak position α and deceleration parameter β. A response surface method visualises overshoot relationships, creating segmented target actions validated through finite element analysis and experimental confirmation, enhancing polynomial precision to minimise overshoot effectively.
