摘要： A system for generating a motion profile in real time includes a processor. The processor breaks a move into a first phase and a second phase. The first phase includes commanding the move toward a constant velocity segment, and the second phase comprises calculating a jerk value required to successfully reach end conditions during a move in progress. The processor also transmits command signals based upon the motion profile and calculates the point at which the second phase must take control to reach a target position. The system further includes a device being controlled for a move and at least one input/output module that receives command signals. A method for generating a motion profile in real time is also presented.

摘要： A method for automatically controlling a flow in a flow line system including a flow line, a flow line inlet and outlet, and a control valve located in the flow line at the outlet. The method includes controlling the opening of the valve with a control unit. An outlet flow rate is measured or estimated from the flow line. The valve is opened. It is determined if a sudden drop occurs in any of the measurements or estimates. It is decided if a liquid blockage in the flow line is present or approaching. If a liquid blockage is indicated as present or approaching, the opening of the valve is increased by an amount determined by the measurements or estimates. Any further manipulation of the valve is inhibited before a non-zero time period has expired. The steps are repeated. Also a system and a computer program product.
