Abstract: PURPOSE: A method for extracting identity parameters in an electric circuit system and a method to determine equivalent circuits are provided to perform system identification in terms of probability about a circuit system and extracting parameter of circuit system which is exposed to irregular noise. CONSTITUTION: A current value which is an output according to noise application of an ordinary differential equation of circuit system to be identified is calculated(S310). The moment equation of the circuit system is calculated from the calculated current value(S320). A candidate identity parameter of the circuit system inverses the moment equation and extracts the equation(S330). If the candidate identity parameter is identically maintained by approving noise which is different each other to ordinary differential equation of the circuit system, they candidate identity parameter is determined as a identity parameter for equivalent circuit(S340).

Abstract: An apparatus for reducing noises of a system modeled by PDE(Partial Differential Equation) and a method thereof are provided to remarkably reduce noises that may occur in a control target system of which governing equation is PDE in time and physical domains. An apparatus for reducing noises of a system modeled by PDE(Partial Differential Equation) includes: a moment response drawing unit(11) which draws a probability moment response of a control target system by interpreting a normal random output in a probability domain of the control target system of which governing equation is PDE in time and physical domains; a characteristic parameter drawing unit(12) which draws a characteristic parameter of the control target system by reverse-converting the drawn moment response; a modeling unit(13) which performs modeling based on ODE(Ordinary Differential Equation) in a probability domain of the control target system by using moment response and the drawn parameter; and a control signal generator(14) which generates a reduction control signal by the disturbance applied from the control target system.

Abstract: A system identifying method using only a system output in a probability region, a device thereof and a recording medium thereof are provided to use only a system output in a probability region which identifies an unknown system parameter by using not both input and output but only random system outputs exposed to irregular disturbance in a system having an irregular input. A system identifying method using only a system output in a probability region comprises the steps of: measuring a system output exposed to irregular disturbance; obtaining a moment response based on the probability analysis as to the measured system output; and obtaining a system parameter by inverse-transforming the moment response. A system for implementing the system identifying method includes a measurement unit(200), a probability analysis unit(220) and a parameter extraction unit(240). The probability analysis unit obtains the moment response based on the probability analysis as to the system output exposed to the irregular disturbance. The parameter extraction unit obtains the system parameter by inverse-transforming the moment response.
