Abstract:	Because each of the position transducers commonly used in industry, i.e. encoders and resolvers, does not inherently measure an instantaneous velocity, some signal processing technique is generally required to improve the accuracy of velocity estimation at each sampling instant. This estimated signal is then used as the velocity feedback signal for the velocity loop control in servo motor drives . The differential position technique commonly used in industry for velocity estimation suffers from a large quantization error, and therefore limits the servo control loop bandwidth. This paper presents both the theoretical analysis and experimental verification of a scheme that uses a fuzzy logic based observer for velocity estimation. The experimental results have shown that the quantization error in the velocity feedback signal can be reduced dramatically when a fuzzy observer is used for velocity estimation.
