Abstract

As we all know, the output of a system is affected by its input and response properties. When the input switches, there must exist a transient process in the output and this transient process is different for different systems due to their different response properties and different dynamic process. However, the response property and dynamic process have rarely been studied in the obtained achievements about the transient process of an intermittent control system. The obtained achievements cannot agree with the real physical process and cannot be applied to study the transient process in engineering.

By introducing the unit step function and taking the intermittent input signal as a piecewise signal, we have studied the transient process. Our research shows that the transient process is related to the response characteristics, historical dynamic information, and control parameters, which agrees well with the real system and can be applied to analyze and optimize the transient process in engineering. Some examples in our paper verify our theoretical achievements.

从响应特性研究间歇控制系统的瞬态过程

众所周知，系统的输出受其输入和响应特性的影响。当输入切换时，输出必然存在一个瞬态过程，而不同的系统由于其响应特性和动态过程不同，其瞬态过程也不同。然而，在已取得的有关间歇控制系统瞬态过程的成果中，很少对响应特性和动态过程进行研究。通过引入单位阶跃函数并将间歇输入信号作为片断信号，我们对瞬态过程进行了研究。我们的研究表明，瞬态过程与响应特性、历史动态信息和控制参数有关，与实际系统非常吻合，可用于分析和优化工程中的瞬态过程。论文中的一些实例验证了我们的理论成果。
