## Abstract The minimum variance control law for a cascade control system is derived for two cases: the primary process has stable and unstable inverses. The expression for the primary output variable under the minimum variance cascade control is shown to be feedback‐invariant. An estimate of the m
## Abstract A monitor is developed to automatically detect poor control performance. It provides a measure (relative performance index—RPI) of a control‐loop performance relative to a reference model of acceptable control. The reference model simulates the controlled variable output of a user‐defin
