The Implementation of the Frequency Analyzer Principle for the Estimation of the Electronically Switched Capacitor's Capacitance
Journal Title: RECENT - Year 2015, Vol 16, Issue 46
Abstract
In this work, the authors investigated the implementation of the frequency analyzer principle to produce real-time estimates of the equivalent capacitance of the electronically switched capacitor for the two-phase induction servo-motor. The on-line estimation of the capacitance of the start-up switched capacitor for the auxiliary phase of the two phased induction motor is subjected to disturbances due to the large commutation voltages. The correlation frequency analyzer is mainly used in systems identification to estimate the dynamic models within the frequency and correlation identification methods. In comparison with the direct data averaging, the frequency analyzer implementation is less noise sensitive, more accurate and subjected to the embedded implementations. The experimental results of this investigation proved that the embedded implementation of the frequency analyzer principle is possible within the same microcontroller that produces the control law for the switched capacitor.
