【摘要】 本文是在感应机可控硅串级调速静态理论[文献1]基础上,着重对系统的动态特性作较为详细的分析与研究。并根据串级调速系统的特点(变参量),提出了切合实可行的控制结构,从理论上论证了该方案的合理性,指出了综合系统参数的依据。利用本文中的公式计算方便,又能获得较好的性能指标,简单易懂,便于在实际工程中应用。更多还原

【Abstract】 Based on the steady-state theory of SCR Cascade adjustable speed iuduction motor drive system [Ref, 1], this paper analyses and studies in detail the dynamic performance of the system, A practicable control structure is proposed according to the characteristics of cascade adjustable speed system. The reasonableuess of the new scheme is proved in theory. The basis for synthesizng system parameter is proposed. Simple calculation aud good performance index can be obtained by mans of the formnlas presented in this paper, which is easy to understaud aud is convent to apply in practical engineering.更多还原
