Patent number: 8144417Abstract: Techniques are provided herein for reducing vibrations in various modes of a dynamic system. One such technique comprises incorporating vibration limiting and sensitivity constraints into a partial fraction expansion equation model of the system so as to reduce vibrations to specific levels. Another technique comprises shaping a command determined using the partial fraction expansion equation model to produce a desired output. The entire command may be shaped or only selected portions thereof which produce vibrations. Another technique involves commanding in current to produce saturation in voltage. By doing this it is possible to command voltage switches. The times at which the switches occur can be set to reduce system vibrations. Other techniques are also provided. These include varying transient portions at the beginning, middle and/or end of a move and using Posicast inputs, among others.Type: GrantFiled: September 23, 2008Date of Patent: March 27, 2012Assignee: Convolve, Inc.Inventors: Neil Singer, Mark Tanquary, Kenneth Pasch

Patent number: 6163116Abstract: Control system for controlling a dynamic physical system. New, substantially decoupled axes are derived from physical axes of a dynamic system. Closed-loop controllers operate on signals representing the new or synthesized axes to control the coordinate parameters. Control signals are then converted into the original physical axes to generate signals to control the original axes. A preferred embodiment is the application of the control technique to a gantry machine having three degrees of freedom. Actual coordinates are converted to one linear coordinate and one rotational coordinate. The bandwidth of controllers operating on these two coordinates are separated so that crosstalk is diminished and performance improved.Type: GrantFiled: March 9, 1999Date of Patent: December 19, 2000Assignee: Convolve, Inc.Inventors: Mark L.

Patent number: 5988411Abstract: Tele-operated machine including a moveable structure and a control device functionally connected to the moveable structure for operation by a human operator. An input processor apparatus responsive to the control device generates signals to move the moveable structure in a reduced vibration fashion. In a preferred embodiment, the tele-operated machine is a crane. The operator can cause fixed length incremental movements of a load supported by the crane to be accomplished with reduced levels of vibration after the move is completed.Type: GrantFiled: April 5, 1996Date of Patent: November 23, 1999Assignee: Convolve, Inc.Inventors: Neil C.

Patent number: 5638267Abstract: Method and apparatus for minimizing unwanted dynamics in a physical system response. Constraints on the input and on the unwanted dynamics are established, and an impulse sequence which satisfies the constraints is determined. The impulse sequence is convolved with an arbitrary command input to produce a shaped input which is used to drive physical system, thereby minimizing unwanted dynamics. The constraints on the input and on the unwanted dynamics may be selected to achieve shaped inputs and residual unwanted dynamics of various characteristics.Type: GrantFiled: June 15, 1994Date of Patent: June 10, 1997Assignee: Convolve, Inc.Inventors: William E.
