控制度分子式：CAS号：性质：(一)控制品质指标的泛称。(二)专指反映离散PID控制所能达到的最佳控制品质与连续PID控制所能达到的最佳控制品质之间差距的指标。由于离散控制系统是周期地取得测量数据的，在一次实测之后，要经过一个采样周期才能获得新的测量信息，采样时刻之间的测量值成为未知值，获取信息的及时性将不如连续控制系统，控制品质受到一定影响。通常把偏差平方值对时间的积分值称为平方积分鉴定(ISE)。对同一个过程，离散PID控制所能达到的最小ISE值与连续PID控制所能达到的最小ISE值之比称为控制度。控制度以下为下限，其值越大，表示离散控制情况下控制品质越差。适当缩短采样周期，可使控制度得到改善。控制度一般应保持在1.2以下。
