Abstract

In this paper, the use of low resolution sensor to achieve high performance speed control is investigated. A speed dependent feedback control is used in conjunction with an input shaper to improve the transient characteristics. The use of a shaper is particularly suitable in this application since the shaper is an open loop scheme, independent of the sensor characteristics. The characteristics of the proposed control scheme is first assessed by numerical simulation, based on a detailed mathematical model of the motor. This is followed by experimental verification. From the simulated and experimental data, it is observed input shaping, using a ZVD Shaper, reduces settling time by 80%. In particular, settling to 10% of command level can be achieved in about 0.1 second. Furthermore, speed dependent control significantly improves motor response when low resolution sensor is used.
