摘要: A method reduces a sway of an elevator rope supporting an elevator car within an elevator system using an elevator sheave. The method controls, using a movement of the elevator sheave, a tension of the elevator rope according to a control law of the tension of the elevator rope between a first point and a second point. The first point is associated with a contact of the elevator rope with the elevator sheave. The second point is associated with a contact of the elevator rope with the elevator car or a counterweight of the elevator car. The control law is a function of one or combination of a relative position, a relative velocity and a relative acceleration between the first and the second points.

摘要: A method for controlling an operation of an elevator system is discloses. The elevator system includes an elevator car moving within an elevator shaft and at least one elevator cable connected to the elevator car and the elevator shaft to carry electrical signals to the elevator car. The method determines a counter force on the elevator cable required to change a nominal shape of the elevator cable to an inverse shape of a current shape of the elevator cable caused by disturbance on the elevator system and applies the counter force to the elevator cable.

摘要: A computer-implemented method is provided. The computer-implemented includes a data-driven model and a robust closure model stored in a memory by using a processor for controlling a system. The computer-implemented method includes steps of acquiring sensor signals from at least one sensor of the system via an interface, computing a state of the system based on the sensor signals, determining a gain of the robust closure model based on the state of the system, reproducing a state of the system based on the determined gain, estimating a physics-based model of the system by combining the data-driven model and the robust closure model, and generating control commands by mapping the state of the system using the estimated physics-based model.

摘要: A controller for controlling a system having uncertainties in its dynamics subject to constraints on an operation of the system is provided. The controller is configured to acquire historical data of the operation of the system, and determine, for the system in a current state, a current control action transitioning a state of the system from the current state to a next state. The current control action is determined according to a robust and constraint Markov decision process (RCMDP) that uses the historical data to optimize a performance cost of the operation of the system subject to an optimization of a safety cost enforcing the constraints on the operation, wherein a state transition for each of state and action pairs in the performance cost and the safety cost is represented by a plurality of state transitions capturing the uncertainties of the dynamics of the system.

摘要: A method and system determines flows by first acquiring a video of the flows with a camera, wherein the flows are pedestrians in a scene, wherein the video includes a set of frames. Motion vectors are extracted from each frame in the set, and a data matrix is constructed from the motion vectors in the set of frames. A low rank Koopman operator is determined from the data matrix and a spectrum of the low rank Koopman operator is analyzed to determine a set of Koopman modes. Then, the frames are segmented into independent flows according to a clustering of the Koopman modes.
