  • Publication number: 20070162161
    Abstract: A method for dynamically controlling a multiple input, multiple output (MIMO) system having multiple input and output constraints, the method comprising. In an exemplary embodiment, the method includes configuring a MIMO tracking controller to implement closed loop tracking of multiple control reference inputs of the system, in the absence of input and output constraints, and configuring a MIMO constraint controller to enforce the input and output constraints of the MIMO system by generating a reference modification applied to the multiple control reference inputs.

  • Patent number: 6952639
    Abstract: A method for estimating a temperature profile for individual combustion cans at an inlet of a gas turbine is disclosed. In an exemplary embodiment, the method includes determining an exhaust temperature profile of exhaust gas of the gas turbine, and inputting the exhaust temperature profile into a model-based estimator of turbine components through which turbine gas flows. The model-based estimator calculates an estimated inlet temperature profile at the gas turbine inlet, based upon the exhaust temperature profile and design parameters of the gas turbine, the estimate inlet temperature profile being indicative of the actual firing temperature of each of the individual combustion cans.

  • Publication number: 20050193739
    Abstract: A method and system of controlling a gas turbine engine is disclosed. The engine has sensors to detect one or more parameters and actuators adapted to respond to commands. The method includes receiving data from the sensors of the engine for one or more measured or sensed parameters, estimating a state of the engine by estimating one or more unmeasured or unsensed parameters using the data from the sensors and a predictive model of the engine, generating commands for the actuators based on the state using an optimization algorithm; and transmitting the commands to the engine. The system includes a state estimator adapted to estimate a state of the engine by estimating one or more unmeasured or unsensed parameters using data from the sensors of the engine for one or more measured or sensed parameters. The estimator includes a model of the engine. The system also includes a control module adapted to generate commands for the actuators based on the state.

  • Patent number: 6823675
    Abstract: Adaptive model-based control systems and methods are described so that performance and/or operability of a gas turbine in an aircraft engine, power plant, marine propulsion, or industrial application can be optimized under normal, deteriorated, faulted, failed and/or damaged operation. First, a model of each relevant system or component is created, and the model is adapted to the engine. Then, if/when deterioration, a fault, a failure or some kind of damage to an engine component or system is detected, that information is input to the model-based control as changes to the model, constraints, objective function, or other control parameters. With all the information about the engine condition, and state and directives on the control goals in terms of an objective function and constraints, the control then solves an optimization so the optimal control action can be determined and taken.

  • Patent number: 6384384
    Abstract: Boil dry conditions are detected in utensils heated on a cooking appliance having at least one energy source disposed under a cooking surface such as a glass-ceramic plate and a controller for controlling the level of power supplied to the energy source. The boil dry detection system includes a temperature sensor for providing a signal representative of the glass-ceramic temperature to the controller. The controller controls the power source in response to the temperature signal so as to prevent the glass-ceramic plate from exceeding a maximum temperature and provides a power signal that is indicative of the level of power being supplied to the energy source. The controller generates an estimate of the first and second derivatives with respect to time of either the temperature signal or the power signal, depending on its operating mode.

  • Patent number: 6350971
    Abstract: An apparatus is provided for detecting movement of a vessel positioned on a cooktop surface. The apparatus includes a resonant circuit that has at least an inductive loop positioned proximate to the cooktop surface. A signal conditioner is connected to the resonant circuit for conditioning signals received from the resonant circuit. A processor is connected to the signal conditioner and compares the conditioned signals received from the signal conditioner to a reference signal whereby detecting movement of the vessel.
