Modes 1-3 are steady state modes with all derivatives set equal to zero. Modes 4-6 are dynamic modes where the differential equations define how the variables change with time. Modes 7-9 are the same as 4-6 except the solution is performed with a sequential versus a simultaneous approach. Each mode for simulation, estimation, and optimization has a steady state and dynamic option.

Modes 2 and 5 are estimation modes. Mode 2 is for steady-state estimation and mode 5 is for dynamic estimation. Mode 2 is also known as the data reconciliation step in a real-time optimization solution. Mode 5 is also known as moving horizon estimation. Mode 5 is equivalent to the Kalman filter when the model is linear, the disturbance noise is white, and the probability ~~distribution~~ function is assumed Gaussian.

Modes 3 and 6 are optimization and control modes. Mode 3 performs steady-state optimization. Combined with mode 2, this constitutes a real-time optimization (RTO) solution. Mode 6 has a similar objective as mode 3 but is solved with a time-varying model. For linear models, this is often referred to as ''control''. For nonlinear models, this is~~ often~~ referred to as ''nonlinear control'' (NLC) or ''nonlinear model predictive control'' (NMPC).

The core of all modes is the non-linear model. Each mode interacts with the nonlinear model to receive or provide information. There are 6 modes of operation for the %blue%A%red%P%black%Monitor software.

# Steady-state simulation (SS)

# Model parameter update (MPU)

# Real-time optimization (RTO)

# Dynamic simulation (SIM)

# Moving horizon estimation (MHE)

# Nonlinear control (NLC)

Modes 1-3 are steady state modes with all derivatives set equal to zero. Modes 4-6 are dynamic modes where the differential equations define how the variables change with time. Each mode has a steady state and dynamic option.

**** Simulation

Modes 1 and 4 are simulation-only modes. These simulation modes are for steady-state and dynamic investigation of the model. There is no optimization with the simulation modes. The model serves as a virtual process or simulator.

**** Estimation

Modes 2 and 5 are estimation modes. Mode 2 is for steady-state estimation and mode 5 is for dynamic estimation. Mode 2 is also known as the data reconciliation step in a real-time optimization solution. Mode 5 is also known as moving horizon estimation. Mode 5 is equivalent to the Kalman filter when the model is linear, the disturbance noise is white, and the probability distribution function is assumed Gaussian.
