摘要： MPC controller systems and methods are disclosed that may be applied to various different types of MPC controllers and methods for use in any desired or appropriate controller settings, such as physical systems with non-linearities that require careful modelling tactics, which are considered complex systems. Complex systems include fast systems which are those where solving the descriptive model of the system has the potential to surpass the closed loop sampling time required to control the system. Examples of complex fast systems are robot manipulators, quadracopters and injection speed of an injection molding process.

摘要： The present invention provides an interval error observer-based aircraft engine active fault tolerant control method, and belongs to the technical field of aircraft control. The method comprises: tracking the state and the output of a reference model of an aircraft engine through an error feedback controller; compensating a control system of the aircraft engine having a disturbance signal and actuator and sensor faults through a virtual sensor and a virtual actuator; observing an error between a system with fault of the aircraft engine and the reference model through an interval error observer, and feeding back the error to the error feedback controller; and finally, using a difference between the output of the reference model of the system with fault and the output of the virtual actuator as a control signal to realize active fault tolerant control of the aircraft engine.

摘要： Systems, devices, media, and methods are presented for controlling remote equipment in a network. A switch heater control system includes a weather modeling function. The system periodically obtains weather data according to a predetermined time interval. Based on the closest weather data set, the weather modeling function generates a hyperlocal forecast associated with each switch heater location. The system includes an active snowfall mode and a maintenance mode that controls heating based on an estimate of local snow depth, adjusted for wind conditions and passing trains. When the hyperlocal forecast indicates heating is required, the system calculates a melt duration, starts a timer, and transmits a start signal to the switch heater.

摘要： A computer-implemented method comprising: receiving data associated with an operational control problem; formulating the operation control problem as an optimization problem; recursively generating a sequence of policies of operational control associated with the operational control problem, wherein each subsequent policy in the sequence is constructed by modifying one or more actions at a single state in a preceding policy in the sequence, and wherein the modifying monotonically changes a risk associated with the subsequent policy; constructing, from the sequence of policies, an optimal solution path, wherein each vertex on the optimal solution path represents an optimal solution to the operational control problem; calculating a ratio of reward to risk for each of the vertices on the path; and selecting one of the policies in the sequence to apply to the operational control problem, based, at least in part, on the calculated ratios.

摘要： A system for representing a set of operating states of a vehicle to a user of the vehicle includes a vehicle having a vehicle operating state, and a digital twin receiving vehicle parameter data from one or more inputs to determine the vehicle operating state. An interface for the digital twin presents the vehicle operating state to the user of the vehicle. An identity management system manages a set of identities and roles of the vehicle user and determines capabilities to view, modify, and configure the digital twin based on parsing of the set of identities and roles.

摘要： Embodiments include a computer-implemented method (and system) for performing automated batch data alignment for modeling, monitoring, and control of an industrial batch process. The method (and system) loads, scales, and screens plant historian batch data for an industrial batch process. The method (and system) selects a reference batch as basis of the batch alignment, defines and adds or modifies one or more batch phases, and selects one or more batch variables based on one or more profiles and corresponding curvatures of the batch data. The method (and system) estimates one or more weightings, adjust one or more tuning parameters and uses a sliding time window combined with DTW, DTI and GSS algorithms, performs the batch alignment in offline mode or online mode.
