Abstract :
This paper presents an event-based discontinuous control scheme for harmonic drive (HD) transmission. It is composed of two control strategies, namely, the motor-side PD control refined by load-side acceleration feedback, and the output torque control. Switching between these two modes is based on the external working condition of the HD. This intends to generate appropriate control actions according to the actual problems of the HD, which are different and closely dependent on its external conditions. Extensive experiments were conducted on a single link device driven by an AC motor and harmonic transmission to test the performance of the proposed scheme
