error of zero meaning in Chinese

零点误差
零位误差

Because quantitative grade of fuzzy area is limited , especially zero area , the system is regarded as stable condition though it has little error . therefore , the output of control is zero , namely the little error of zero area is n ' t be controlled . in addtion , in the process of the choice of parameters of single fuzzy controller , not only should we consider that when error is large , the main task of control system is to eliminate error , but also we should consider that when error is little , the main task of control system , is to diminish super regulation , so that the system can be stable more quickly . from the view of the control results , there exists little error when system is stable , namely so - called stable error
由于模糊论域的量化等级是有限的，特别是在零域内，尽管有误差(误差很小) ，系统也被认为处于稳定状态，于是控制输出为零，即零域内的小偏差没有得到控制；再加上单模糊控制器在参数的选取时，既要考虑当误差较大时，控制系统的主要任务是消除误差；又要考虑当误差较小时，控制系统的主要任务是减小超调量、使系统尽快稳定下来。
