FEATURES OF HARMONIC LINEARIZATION OF NONLINEAR ELEMENT IN CONTROL SYSTEMS OF AERIAL VEHICLES WITH THE DIGITAL COMPUTER ONBOARD

Abstract

Reviewed features of harmonic linearization of nonlinear element in control systems with the digital computer onboard (DCO) in the circuit of control. Difficulties of this task solution become more complicated because of the system of automatic control with DCO in the circuit of control naturally is continuous-discrete system (CDS). The main characteristic of CDS is signal interruption in one or many points of the system with saving uninterrupted outgoing system signal. It was proved that depending on mutual arrangement of nonlinear and impulse elements in the structure of CDS it is necessary to use different coefficients of harmonic linearization of nonlinear element. This will allow more closely take in account of possible system periodical modes and increase the precision of its parameters determination.
