要約(英語): In this paper, diode-clamped linear amplifiers (DCLAs) are developed for achieving low-noise and fine force control. Class-B and Class-D power amplifiers are not suitable for driving a motor, owing to their power efficiency and high switching noise. In particular, a force control system using Class-D power amplifiers cannot generate appropriate fine force because of the switching operations by PWM or PDM. For that reason, we focus on DCLAs, which are capable of solving the problems both power efficiency and force noise. Furthermore, the force noise generated by the linear motor is less than that generated by the Class-D power amplifiers. Through a theoretical analysis, simulations, and experiments, the validity of the force control system using DCLAs is verified.
