Abstract

In this work, we propose a new technique to improve the transient response of the comb drive actuator using a digital compensation technique. This technique is mainly based on the use of a specific digital pulse train that satisfies the equal area criterion on the force displacement diagram of the actuator. Applying this technique to a specific actuator design, we show that it increases the forward displacement without sticking, reduces the overshoot, and improves the speed of response.
