Title: Drive control device and method, image forming device, image reader, and program
Inventor: KOMATSU MAKOTO
IPC: H02P29/00
Filed: 2003-11-06
Abstract: <P>PROBLEM TO BE SOLVED: To reduce, even when using a low-resolution, inexpensive sensor, the maximum amount of deviation from a desired position such as a belt, which deviation could occur after a joint between marks or the like has been passed.  <P>SOLUTION: When the joint or the like between linear scales 108 exists in the detection area of a surface sensor 109, a discontinuous part appears in the output pulses thereof. When the discontinuous part does not exist, feedback control is effected using multiplied pulses obtained by multiplying each output pulse up to 64 times. When the discontinuous part exists, dummy pulses taking the place of the multiplied pulses are used to effect feedback control. The feedback control effected using such multiplied pulses has the effect of enhancing the apparent resolution of even a low-resolution surface sensor. As a result, the maximum amount of deviation between the position of the belt 106 and the desired position, which could occur immediately after the period of the discontinuous part has ended, can be reduced.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Filed: 2003-11-11
Abstract: <P>PROBLEM TO BE SOLVED: To provide a control device for a variable valve system capable of simplifying control being stable and extremely low in following delay.  <P>SOLUTION: An ECU calculates a target working angle (r) and a difference between the target working angle and a last time target working angle value (r)' being 2ms before memorized by processing of a block 31 is determined by a block 32 as a variation speed (v) to be feed-forward-controlled. Further, from the target working angle (r) and a real value inputted from a sensor, a deviation to be corrected is determined by feedback control and regarded as a virtual speed (u). The variation speed (v) and the virtual speed (u) are added through processing of a block 33. From an added set variation speed (v+u) and the inputted target working angle (r), a stored three dimensional map M3 is referred to determine a voltage E being a control amount to be outputted.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
