Abstract: A computer system independently maintains states of multiple condition indicators as logical state data, each indicator for a different respective condition and having at least an active and inactive state. Multiple condition indicators share a single human-perceptible physical indicator having at least (N+1) states, where N is the number of condition indicators, the physical indicator states including a state for all conditions inactive, and a respective separate state for each respective condition active. Preferably, the conditions comprise a fault condition and an identify condition, and the physical indicator is a light which is off if neither condition is active, is constant on if the fault condition is active, and is flashing if the identify condition is active.

Abstract: System and method to estimate variables in an integrated gasification combined cycle (IGCC) plant are provided. The system includes a sensor suite to measure respective plant input and output variables. An extended Kalman filter (EKF) receives sensed plant input variables and includes a dynamic model to generate a plurality of plant state estimates and a covariance matrix for the state estimates. A preemptive-constraining processor is configured to preemptively constrain the state estimates and covariance matrix to be free of constraint violations. A measurement-correction processor may be configured to correct constrained state estimates and a constrained covariance matrix based on processing of sensed plant output variables. The measurement-correction processor is coupled to update the dynamic model with corrected state estimates and a corrected covariance matrix. The updated dynamic model may be configured to estimate values for at least one plant variable not originally sensed by the sensor suite.
