<P>PROBLEM TO BE SOLVED: To prevent the energy efficiency of the circuit from being reduced thereby avoiding dissipated heat from causing increase in the overall temperature of a control panel when drive energy is converted to heat through a linear drive circuit. <P>SOLUTION: The method may include the steps of receiving a direction control signal, manipulating one or more devices to establish at least one switchable positive current path and at least one switchable negative current path through an actuator based at least in part on the direction control signal, providing feedback based at least on current associated with the actuator, and controlling the current based at least in part on the feedback. The method may include manipulating one or more devices to establish at least one positive current path and at least one negative current path through an actuator via hysteresis control. <P>COPYRIGHT: (C)2012,JPO&INPIT |
