Superharmonic resonance bifurcation control of parametrically excited system based on state feedback strategy
基於狀態反饋參數激勵系統的超諧共振分岔控制In chapter 4, the bifurcation of the complex nonlinear oscillator of van der pol - duffing - mathieu ' s is studied and the common bifurcation property of the oscillator in the situations of nonresonance, principal resonance, ultraharmonic resonance and non - subharmonic resonance is revealed. the bifurcation of strongly nonlinear oscillator is also explored in this chapter
第四章對非線性振動中最常見的vanderpol - duffing - mathieu復合非線性振子的分岔性質進行了系統的研究,發現了該復合系統在非共振、主共振、超諧共振和非1 2階次諧共振情況下具有相同的分岔特性。Using this method not only the necessary condition of existence and the approximate analytic expressions of the periodic solutions for primary - harmonic, super - harmonic and sub - harmonic resonances can be obtained, but the criteria of stability for these solutions can also be gained
該方法給出了二階強非線性非自治系統主諧波共振和超諧波、次諧波共振周期解存在的必要條件,求得了這些周期解的近似解析表達式,並且得出了解的穩定性判據。Since the concept of superlattice was proposed, vertical transport in superlattice has been investigated widely. the electric field domains and current self - oscillations which result from sequential resonant tunneling between different subbands of the superlattice are very significant phenomena. such kind of oscillation can be uesd to make tunable microwave oscillaors. in this thesis, low temperature transport problem, especially the formation of field domain and the condition of current self - oscillations in doped gaas / alas superlattice with weak coupling are investigated thoroughly and also by combining the macroscopic model with the microscopic one., the voltage - current characteristic and the current oscillation are simulated. the calculated result is nearly consistent with the experimental data
