Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Using the Legendre polynomials when automatic parametric optimizationfor automatic systems with the pulse-amplitude modulations N.N. KUCYI, DUC THANG NGUYEN Represented the approach to solving problem of single valued representation of adjustable parameters value using orthogonal Legendre polynomials when forming modulation characteristic of impulse element and building sensitivity analyzer for automatic systems with the pulse-amplitude modulations (PAM) based on these polynomials. Bring results of research the automatic parametric optimization algorithm for systems with PAM. Key words. sensitivity analyzer, orthogonal Legendre polynomial, pulse-amplitude modulation, sensitivity theory, automatic parametric optimization algorithm. E-mail: thangnd304@yahoo.com
