Abstract
A method for positioning an object by an electromagnetic motor which, in use, produces a plurality of primary forces and a pitch torque associated with the primary forces. The method includes a cycle which includes: determining the desired forces and torques for positioning the object, determining the primary forces to be generated by the motor, determine the pitch torque from either the primary forces or from the desired forces and torques, determine the desired signals for the motor to generate the primary forces. In a next cycle, prior to the determination of the primary forces, the desired forces and torques for positioning the object are modified using the pitch torque determined in the previous cycle of steps.
