专利汇可以提供Position control system专利检索,专利查询,专利分析的服务。并且PURPOSE: To access an aimed track at high speed by comparing a status value to express the present speed, acceleration and position of a head during movement with a switched curved surface, and controlling the speed for the head with a deviation value.
CONSTITUTION: To position a head 7 on a magnetic disk 8 to the aimed track, a high-speed memory device 10 receives an aimed position signal S
0 from a host computer. In addition, the device 10 reads a position signal S
6 , an actual speed signal S
5 and an actual acceleration signal S
9 to be the status values at the present time of the head 7 from a position detector 6. Further, the deviation between the switched curved surface stored in a status space concerning the head 7 beforehand and the present condition value is calculated, and the operating quantity for the head is decided by the deviation. The normalized operating quantity is outputted to a power amplifier 3, the amplifier 3 drives an actuator 4, and the status values S
5 and S
6 and S
9 of the head 7 are controlled.
