<P>PROBLEM TO BE SOLVED: To provide a DC motor controller capable of solving the problem that a difference between a theoretical moving distance and a measurement is accumulated for a more increase with the passage of time. <P>SOLUTION: This DC motor controller includes a hard logic circuit which controls a preset value of PID feedback control as a position for each elapsed time without being done as a speed. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
