摘要： A method for computer aided design of a product or process. The method includes the steps of representing a computer-aided design activity as a design cycle. The design cycle is then converted into individual iterations of decisions to be made within the design cycle. The individual iterations of decisions are then mapped into a hierarchical structure of influence diagrams. The decision making process of the influence diagrams are performed and data is collected from the decision process that has been performed. The remaining unexecuted decisions and their posterior probabilities are updated based upon the outcomes of the decision process that was most recently performed.

摘要： The present invention includes a method and system for limiting the ramp rate of a variable under control in order to control stress in a process or plant under control. The present invention takes a limit curve provided by the user and combines that limit curve with a scale factor curve obtained from a model of the system to produce an allowable limit curve. A ramp rate limiter then uses the allowable limit curve to control the ramp rate of the variable under control such that the ramp rate of the variable under control is able to achieve the maximum allowable limit but no more.

摘要： A method is disclosed for automatic synthesis of multi-variable controllers. A design sequence for designing a controller for a system is selected, wherein the controller includes one or more controller components. A first set of parameters associated to the one or more controller components is then selected. A second set of parameters associated to the first set of parameters is subsequently selected. One or more parameters of the second set are then iteratively modified to obtain a set of modified parameters, until a plurality of performance characteristics calculated using the second set of parameters meets a performance objective for the system.

摘要： The present invention includes a method and system for reducing switching transients via large signal/small signal thresholding. The present invention prevents a switch from occurring if when the system (i.e., the system under control) is in small signal mode and permits switches to occur when the system is in large signal mode. Large signal and small signal modes are determined by comparing the difference between the most current value of a comparator variable and the final setpoint with a threshold distance. The system is in small signal mode if the most current value of the comparator variable less the final setpoint value is less than the threshold distance. Otherwise, the system is in large signal mode.
摘要翻译：本发明包括用于通过大信号/小信号阈值处理来减少开关瞬变的方法和系统。本发明防止当系统（即被控制的系统）处于小信号模式时发生切换，并且当系统处于大信号模式时允许开关发生。通过将比较器变量的最新值与最终设定值之间的差与阈值距离进行比较来确定大信号和小信号模式。如果比较器变量的最大电流值小于最终设定值小于阈值距离，系统处于小信号模式。否则，系统处于大信号模式。
