抄録

This paper describes an effective way to achieve precise information necessary for systems, such as traction drives, where low-resolution position sensors are commonly used. To solve this problem, the authors propose an estimation scheme called multirate sampling observer, which can estimate the state variables during the interval of two consecutive pulses from such sensors. The authors also propose a novel pole placement method that stabilizes the observer in especially in low speed range. The effectiveness of the observer is verified through various simulations and experiments.
