摘要： A method and system for operating a CO2 refrigeration system is provided. Two pressures are controlled by two controllers through two valves in this system. A first valve is actuated by a first controller using a first transfer function in response to the first measured pressure. A second valve is actuated by a second controller using a second transfer function in response to the second measured pressure. When it is determining the second valve failed to operate correctly, the first valve is actuated by a third controller using a third transfer function.

In addition, the method includes providing a second output signal, where the second output signal is operable to control at least the portion of the process. The second controller may be operable to use the second output signal to generate the first output signal.

摘要： A technique for fast performance prediction of multivariable model predictive controllers (MPC) for large-scale spatially-distributed dynamic systems is provided. When operating an MPC for a two-dimensional sheetmaking process, the controller's performance can be separated into spatial performance and dynamic performance. The steady-state spatial performance for different sheet property modes is first predicted, thereafter, the dynamic performance is predicted on the basis of the steady-state actuator profiles. During the steady-state spatial performance prediction, the original MPC's cost function is approximated to be a steady-state cost function. Then the steady-state measurement profiles and the actuator profiles are calculated through the steady-state cost function. The actuator profiles in time series can be efficiently solved by minimizing the difference between the actuator profiles and the steady-state actuator profiles in the face of constraints. Finally, the model can be employed to expeditiously compute the measurement profiles in times series.

摘要： A method is provided for commissioning a combustion control system for controlling operation of a boiler combustion system. The method includes the step of mapping a plurality of sets of coordinated servo positions for the fuel flow control device and the air flow control device at a plurality of selected firing rate points between a minimum firing rate and a maximum firing rate by using an algorithm and an iterative process to identify the coordinated air and fuel actuator positions instead of a trial and error method.
