Abstract:
This crane control apparatus and method with swing control and variable impedance is intended for use with overhead cranes where a line suspended from a moveable hoist suspends a load. It is responsive to operator force applied to the load and uses a control strategy based on estimating the force applied by the operator to the load and, subject to a variable desired load impedance, reacting in response to this estimate. The human pushing force on the load is not measured directly, but is estimated from measurement of the angle of deflection of the line suspending the load and measurement of hoist position.
