摘要： Torsional vibrations in a rotating structure having a relatively large mass and subject to varying frequencies of torsional excitation are damped by determining the frequency of torsional excitation of the rotating structure and coupling to the rotating structure a damping pendulum of smaller mass to provide an absorber unit rotating therewith. The angular displacement of the damping pendulum relative to the rotating structure is continuously monitored, and the frequency of excitation is determined. The monitored displacement of the damping pendulum together with the mass damper characteristics of the absorber unit are processed to output a signal which produces a control torque on the damping pendulum proportional to the monitored displacement of the damping pendulum with a controlled time delay to produce control torque on the damping pendulum substantially equal to the torsional excitation of the rotating structure. This produces resonance of the damping pendulum substantially at the torsional excitation of the rotating structure which is effective to damp the vibrations of the rotating structure.

摘要： A system for extracting a signal component from an output signal of a dynamic system. The system comprises a state observer and a corrector filter. The state observer is adapted to track a signal component that represents dominant dynamics in the output signal of the dynamic system and provide an estimation signal representing an estimated signal component in the output signal of the dynamic system. The corrector filter is adapted to compensate for a mismatch between the estimation signal and the actual signal component that represents the dominant dynamics in the output signal. A combination of the estimation signal with an output signal of the corrector filter can provide a synthesized signal including the signal component that represents the dominant dynamics in the output signal.

摘要： A method for moving a substrate to a predetermined location with a specified orientation with a robotic manipulator, the robotic manipulator having a plurality of joint actuators and an end-effector for holding the substrate, wherein the end-effector is independently rotatable with respect to the remaining robotic manipulator. The method can select a reference point on the end-effector for determining a position of the end-effector, wherein the reference point is offset from a wrist of the robotic manipulator, determining a motion path for movement of the end-effector of robotic arm toward predetermined location with specified orientation, and generating motion profiles for translational and rotational components of movement of the end-effector of robotic manipulator along the motion path. The motion profiles are converted into joint motion profiles for each of the joint actuators of the robotic manipulator for implementing the movement of the end-effector to predetermined location with the specified orientation.

摘要： A system for providing the reliable and numerically efficient generation of time-optimum trajectories with easy-to-track or continuous acceleration profiles for simple and blended moves of single- and multi-arm robotic manipulators, such as an extension and retraction move along a straight line or a rotary move following a circular arc, with velocity, acceleration, jerk, and jerk rate constraints. A time-optimum trajectory is the set of the position, velocity, and acceleration profiles which describe the move of a selected end effector along a given path in the shortest time possible without violating given constraints, with a special case being an optimum abort trajectory, which brings the moving arm into complete rest in the shortest time. The invention involves firstly identifying the set of fundamental trajectory shapes which cover all possible combinations of constraints for a given category of moves, e.g., a move along a straight line or along a circular arc; next, decomposing the fundamental shapes into segments where a single constraint is active; and, then, determining the time optimum paths in the segments. As a result, a unique design of time-optimum trajectories is produced based on a set of pre-defined trajectory shapes. The invention also involves the blending of simple moves into a single trajectory by decomposing trajectories of the individual moves into their orthogonal components and overlapping them for a given time interval, which results in a non-stop move along a smooth transfer path.
