采用时滞反馈对振动压路机用永磁直流电动机系统进行反控制，从而实现一种新的电动混沌压路机。首先，建立了逆控永磁直流电机系统的动力学模型和所提出的电混沌压缩器。其次，推导了一个非线性映射，分析了逆控制永磁直流电机系统的混沌判据。然后，数值计算被用来研究所提出的电混沌压缩机的动力学。最后，一系列的仿真进行了验证，建议的电动混沌压实机不仅提供了更好的压实效果比传统的，但也提供了更高的灵活性比机械混沌压实机。
The purpose of this paper is to employ time-delay feedback to anti-control a permanent magnet DC (PMDC) motor system for vibratory compactors, and hence implement a new electrically chaotic compactor. Firstly, the dynamic model of the anti-controlled PMDC motor system and the proposed electrically chaotic compactor are formulated. Secondly, a nonlinear map is derived to analyze the chaotic criterion of the anti-controlled PMDC motor system. Then, numerical computations are used to investigate the dynamics of the proposed electrically chaotic compactor. Finally, a series of simulations are conducted to verify that the proposed electrically chaotic compactor not only offers better compaction effects than the conventional one, but also provides higher flexibility than the mechanically chaotic compactor.
