摘要

The paper deals with analysis of fundamental performance limitations of elastic servo drives with significant mechanical compliance in the driven load. Two-mass system is chosen as a general representation of a flexible mechanism with oscillatory dynamics. A problem of PID compensator tuning is considered since this control algorithm is still prevalent in industrial motion control systems. The provided analysis reveals an essential importance of the resonance ratio parameter and derives its range suitable for convenient controller design. The theoretical analysis is supported by experimental results.
