摘要： Embodiments of methods and systems for controlling a load generated by a power generating system may include controlling at least a portion of the system using model-based control techniques. The model-based control techniques may include a dynamic matrix controller (DMC) that receives a load demand and a process variable as inputs and generates a control signal based on the inputs and a stored model. The model may be configured based on parametric testing, and may be modifiable. Other inputs may also be used to determine the control signal. In an embodiment, a turbine is controlled by a first DMC and a boiler is controlled by a second DMC, and the control signals generated by the first and the second DMCs are used in conjunction to control the generated load. Techniques to move the power generating system from Proportional-Integral-Derivative based control to model-based control are also disclosed.

摘要： In one implementation, an environmental controller operates a cooling system in an electronic device. The environmental controller includes a closed loop control system for operating a cooling fan at a target speed. The environmental controller may select the target speed based on one or more temperature sensors. The environmental controller may select the target speed based on the speeds of additional fans or the fans may be controlled in unison. The closed loop control system includes a proportional weight. When a measured cooling fan speed deviates from the target speed by more than a threshold error value, the proportional weight is constant. As the measured cooling fan speed approaches the target speed, and the threshold error value is crossed, the proportional weight is variable. The variance may be a function of time such as a periodic stair step function.

摘要： A gaseous fluid-operated ozone supply unit includes a housing, output duct, ozone generator, an induction member and controller, the an induction member is located between the air inlet portion and ozone generator of the housing. The output duct has a coupling end and an extension end. The coupling end is connected with the ozone outlet, while the extension end is extended to a preset target for the ozone. The preset target must he capable of guiding the stream so that the output duct could generate negative pressure. The ozone supply unit provided enables to control ozone's opening and closing state through air-operated negative pressure. The ozone supply unit can maintain the flow rate and smoothness of the water supply passage, so as to remove impurities and dirt in water and prevent blocking or even disabling of active magnetic inductor for improved applicability and ease of operation.

摘要： A servomotor control circuit for an air conditioner apparatus of a vehicle includes a drive control section for controlling drive of a servomotor so that the servomotor attains a target stop position, a rotation position change detection section for detecting a change in the rotation position of the servomotor, and an operation limit check section for checking, based on the change in the rotation position of the servomotor, whether the servomotor has attained the operation limit position. The drive control section stops drive of the servomotor without reception of a servomotor drive stop command produced from a main control apparatus, when the servomotor is determined as having attained the operation limit position.

摘要： A multi-stage condition control system of the time proportional type is shown. The control system utilizes a counting means as part of the anticipation for system control. The counting means counts during the time the control system is within its proportional band. When the control system moves outside of the proportional band, the counting stops. A count detection circuit senses the absence of counts thereby indicating that the system is outside of the proportional band. The absence of counts is then used to increase or decrease multiple stages of condition control equipment to bring the system back within the proportional band.
