Abstract

The article is devoted to rejection of unwanted dynamic reactions of flexible structures. The problem of vibrationless movement of an elastic object when natural oscillations are absent and the reaction of the system does not exceed the static reaction is considered. To analyze the oscillations of the system, the maximum response spectrum and the residual spectrum are used. The vibrationless movement property is defined as restrictions on these spectra specified by the control signal. The problem of vibrationless movement is solved by input shaping methods. The shaping filter built on fixed values of the eigenfrequencies of the system is unstable when the frequencies deviate from the set values. To solve this problem, robust modifications of the method are proposed. The high complexity of the considered problem requires computer modeling. In particular, using computer modeling, the problem of the choice of a shaping filter with the property of maximum robustness is solved.
