Applied Physics and Mathematics Annotation << Back FORMATION OF THE TRACKING SYSTEM WHILE LIMITING ITS BANDWIDTH V.G. REUTOV In the design of control systems and, in particular, high-precision angular tracking systems of opto-electronic devices often need to take into account the limitation of the system bandwidth due to the negative impact of non-rigidity, backlash and other kinematic transmission errors, as well as friction. System analytical synthesis under these conditions are generally not practically possible and developers use linearization and numerical methods to fi nd optimal parameters of the elements, forming the control signals. The article discusses the approach to the problem solving, in which the initial design stage bandwidth limitation caused by the infl uence of these factors, replaced by the introduction to the inlet system an additional so-called «colored» noise with the spectral density increasing with the frequency and analytically solve the problem of choosing the optimal structure of the system. Then, using a mathematical simulation carried out a numerical search for the optimal values of the system parameters. Keywords: tracking system, limiting the bandwidth, «colored» noise.
