热熔胶涂布机的一般控制结构

　　通常的热熔胶涂布机控制系统中一般控制结构与其他自动化机器相同，业已形成了相对稳定的模式，知识库由数学过程模型、辨识与估计算法、控制器运行方法和控制性能判据组成。由于热熔胶涂布机自动化系统的实时约束、任务的非线性、有限的执行器速度和范围、鲁棒性、算法的明晰性、可维护性等因素的存在，—些基本的设计要求限定了算法的执行，重要的是，机电过程与控制的同步设计，即系统的静态和动态性质，执行器的类型和位置，传感器的类型和位置，均要适当地设计，使全局的控制性能良好，所以在实时条件下只能用简单的算法或软件模块来完成控制任务，一些热熔胶涂布机机电一体化系统采用较低层的一般控制结构。

　　In general, the general control structure in the control system of the hot melt adhesive coating machine is the same as that of other automatic machines, and has formed a relatively stable mode. The knowledge base is composed of mathematical process model, identification and estimation algorithm, controller operation method and control performance criterion. The hot melt adhesive coating machine automation system, the task of real-time constraints nonlinear, limited actuator speed and range, robustness of the algorithm, understandability, maintainability and other factors, some of the basic design requirements limit the algorithm implementation, the most important is the design of mechanical and electrical control and synchronization process that is, the static and dynamic properties, implementation of the type and location of the type and location of the sensor are designed properly, the overall control performance is good, so in real time under the condition of only using simple algorithm or software module to complete the control task, some hot melt coating machine adopts the general control of mechatronics system the structure of the lower layer.
