ANALYSIS OF THE CRITERION IN CONJUNCTION WITH THE NYQUIST THEOREM FOR THE PARAMETERS IDENTIFICATION OF THE MECHANICAL SYSTEMS.
ABSTRACT. AN APPROPRIATE TIME INTERVAL SEARCH CRITERION AND THE NYQUIST THEOREM ARE USED IN THE NUMERIC SOLUTION OF A SET OF DIFFERENTIAL EQUATIONS IN A TIME AND FREQUENCY DOMAIN PARAMETER IDENTIFICATION PROCESS. IN THIS METHOD, A NUMERIC FACTOR/PARAMETER IS USED TO PROVIDE THE USER WITH A BETTER CONTROL UPON THE SEARCH FOR THE BEST TIME INTERVAL AND RANGE OF FREQUENCIES TO BE USED IT BOTH DOMAIN. ONE METHOD FOR RESOLUTION OF THE SYSTEMS DIFFERENTIAL EQUATIONS IS PROPOSED. THIS TECHNIQUE HAS BEEN SUCCESSFULLY APPLIED TO THE SOLUTION OF MECHANICAL SYSTEMS WITH ONE AND SEVERAL DEGREES OF FREEDOM. THIS TECHNIQUE HAS BEEN SUCCESSFULLY APPLIED TO THE SOLUTION OF MECHANICAL SYSTEMS WITH ONE AND SEVERAL DEGREES OF FREEDOM, IT WAS SHOWN TO BE VERY EFFICIENT IN AN IDENTIFICATION PARAMETERS PROCESS.
