一、批量过程与批量控制 1.批量过程在工业中有不少过程,它们既不是连续的,又有别于断续,而是一个批量一个批量地进行的。在每个批量周期内,过程是连续的;但在两个批量之间,过程是断续的,这种过程称为批量过程。化学工业中的发酵罐、食品工业中的烘炉、冶金工业中的炼钢炉等都属于批量过程。批量过程当然也要求控制,如发酵罐的温度控制。但是,如果用常规的带有积分作用的调节器去控制,那么无论怎样调试和整定,在开始新批量过程时,系统都免不了要出现很大的超调和振荡。批量过程的特点是在批量间歇期内,被调量远离
First, the batch process and batch control 1. Batch process in the industry there are many processes, they are neither continuous, but also different from intermittent, but a batch of a batch. In each batch cycle, the process is continuous; but between two batches, the process is intermittent, a process known as a batch process. Fermenters in the chemical industry, ovens in the food industry, steel-making furnaces in the metallurgical industry, etc. belong to batch processes. The batch process also of course requires control, such as temperature control of the fermentor. However, with conventional regulators with integral action, the system will inevitably experience large overshoots and oscillations at the start of a new batch, no matter how commissioning and tuning are done. Batch process is characterized by batch interval, was measured away from
