Abstract
Positioning apparatus comprising driving apparatus to a load, position sensing apparatus coupled to the driving apparatus, apparatus for sensing input power to the driving apparatus, inaccuracy compensation control apparatus receiving a first input from the position sensing apparatus indicating the position of the driving apparatus and a second input from the apparatus for sensing input power and providing a compensated output indication indicating the position of the load on the basis of information regarding non-linearities in position changes between the driving apparatus and the load including information indicative of whether or not the load is driving the driving apparatus or the driving apparatus is driving the load.
Claims31
A positioning apparatus comprising:
- driving means;
- transmission means coupled to said driving means and to a load;
- position sensing means coupled to said driving means;
- means for sensing input power to said driving means;
- inaccuracy compensation control means receiving a first input from said position sensing means indicating the position of said driving means and a second input from said means for sensing input power and providing a compensated output indication indicating the position of the load on the basis of information regarding non-linearities in position changes between the driving means and the load including information indicative of whether or not the load is driving the driving apparatus or the driving means is driving the load.
A positioning apparatus comprising:
- driving means;
- transmission means coupled to said driving means and to a load;
- position sensing means coupled to said driving means;
- means for sensing input power to said driving means;
- inaccuracy compensation control means receiving a first input from said position sensing means indicating the position of said driving means and a second input from said means for sensing input power and providing a compensated output indication indicating the velocity of the load on the basis of information regarding non-linearities in position changes between the driving means and the load including information indicative of whether or not the load is driving the driving means or the driving apparatus is driving the load.
A positioning apparatus comprising:
- driving means;
- transmission means coupled to said driving means and to a load;
- position sensing means coupled to said driving means;
- means for sensing input power to said driving means;
- inaccuracy compensation control means receiving a first input from said position sensing means indicating the position of said driving means and a second input from said means for sensing input power and providing a compensated output indication indicating the force at the output of the transmission means on the basis of information regarding non-linearities in position changes between the driving means and the load including information indicative of whether or not the load is driving the driving means or the driving means is driving the load.
The positioning apparatus according to claim 33 wherein said inaccuracy compensation control means also comprises indicating means operative to indicate the position of the load even when the positioning apparatus is at rest, said indicating means comprising means for increasing or decreasing the input power until quasi-static movement of the load is reached.
