摘要
误差平方积分性能指标着重权衡大的误差,较少考虑小的误差,其选择性不是很理想。为了改善误差平方积分性能指标的不足,提出采用信息熵为性能指标,通过计算机仿真比较误差平方与信息熵性能指标在加工过程模糊控制中的应用,仿真表明熵性能指标能够综合评价控制系统的动、静态性能。
The indices of error square integral measure great error mostly and measure little error less. Its selectivity is poor. Entropy is used as performance index for to improve shortage of error square. And the performance of entropy are compared to that of Error Square with simulation in machining fuzzy control. The results show that the index of information entropy has a better comprehensive performance than that of error square sum and it can evaluate synthetically performance of dynamic and static state in control system.
