摘要
为校验数控系统运行时的逻辑与性能可达性,引入了基于网论原理的系统动态建模与分析技术。提出了带抑制弧TTPN的有条件等价转换策略,可有效降低分析模型的维度与复杂度。建立了系统运动控制相关过程的分析模型,经等效转换处理后进行了仿真分析,并给出了系统调整的量化依据。仿真表明经调整后的系统能达到预期指标。
In order to check the realizability of CNC system runtime logic and performance, technology of system dynamic modeling and analyzing based on net theory was introduced.A strategy of conditional equal-transformation of TTPN with inhibitor arc was proposed,which will descend the model dimension and decrease analyzing complexity.An analyzing model of the system motion control-associated processes was built,which was then transformed equivalently according to the foregoing strategy.With that model,a simulation was carried out and the quantitative basis for the system structure adjusting was given.Further simulation illustrates that the adjusted system is able to achieve expected performance.
