本文对电子万能试验机控制系统进行了综合分析、设计和实现，并将全系统分为三环（内、中、外环），由内向外逐层实施。其中内环为直流伺服单元，该环主要提供功率驱动和良好的动静态性能，中环为模数混合锁相系统，期望利用锁相技术的高稳态精度达到设计要求。外环针对试件的差异以及在拉压时的非线性，引入实时递推辩识和自校正控制，该控制器为新型的跟踪任意给定输入零极点配置自校正方案，与常规的零极点配置方法相比，具有好的跟踪性能和减小输出抖动的能力。仿真结果验证了这种方法的有效性。
In this paper, the electronic universal testing machine control system for a comprehensive analysis, design and implementation, and the whole system is divided into tricyclic (inner, middle and outer ring), from the inside to the outside layer by layer implementation. The inner ring is a DC servo unit. The ring mainly provides power drive and good dynamic and static performance. The middle part is a modular mixed phase locked system, and the high steady state precision of the phase locking technology is expected to meet the design requirements. For the difference of the outer ring and the non-linearity of the outer ring during tension and compression, the recursive real-time recursion identification and self-tuning control are introduced. The controller is equipped with a new self-tuning scheme for tracking any given input zero-pole. Compared with the conventional zero-pole Compared with the configuration method, with good tracking performance and reduce the output jitter ability. Simulation results verify the effectiveness of this method.
