Determination of Circuit Parameters for Oscillator using Invariant

摘要

This paper presents the method to determine circuit parameters for oscillator the invariant based on symmetry using Gobner base. Grobner base is powerful tool based on computer 3, 4, and its advantage is that we can analyze system with parameters. The reports 5~9 presented analysis of circuit systems using harmonic balance method by viewing the harmonic balance equation as the equation of state variables. Whereas, The proposed method is possible by viewing the circuit equation as not the equation of state variables but the equation of circuit parameters. Using the method, we can clarify relation between each parameter and the constraint of parameters.
