摘要： A feedback control system for producing a PWM control signal for feedback controlling an object according to control error data is disclosed. Control data for producing the PWM control signal produced according to control error data and previously stored rounding error data are added together. The sum of the control data and rounding error data is rounded off, while the rounding error data is stored in a register (6), a memory, etc. The PWM control signal is produced according to the rounded-off data.

摘要： A microcomputer (20) servo control the rotational speed and the rotational phase of a cylinder motor (37) of a VTR in a digital manner. The microcomputer (20) generates a 10-bit digital phase error signal D PH having sufficiently low conversion gain and a 10-bit digital speed error signal D SP having sufficiently low conversion gain in response to an FG signal generated with rotation of a cylinder motor. The digital phase error signal D PH and the digital speed error signal D SP are added to each other in a digital manner in the addition ratio 1:8. In addition, this result of addition is amplified by four times in a digital manner by extracting eight lower order bits thereof and then, converted into an analogue signal and supplied to the cylinder motor as a servo control signal. Thus, since the error signals are added to each other in a digital manner and then, the added signal amplified as required, a digital servo having a large capture range can be achieved as whole.

摘要： A thermally developed photographic copier is provided having two controls, one for adjusting the contrast, or blackness, of an image, and another for adjusting background contrast. A microprocessor samples and processes the settings of these controls to produce a video pedestal determined by the background contrast control, and a gain control signal adjusted for effects of the background contrast setting to keep amplified video signals within the dynamic range necessaryforthe image contrast setting. Video signals used to expose light-sensitive paper or film are amplified in accordance with the gain control signal and combined with the video pedestal for desired background contrast. The system can automatically modify the gain and video pedestal levels for different lots of paper or film by recording a calibrated grey scale, scanning the recorded grey scale image, comparing the scanned image with previously stored information on the desired image, and modifying the gain and pedesial values as necessary to reproduce images of the desired appearance.

摘要： A hard copy recorder is provided in which paper or film is moved along a paper path by a motor-driven roller. A tension-measuring dancer measures paper or film tension. The position of the dancer is sensed by an optical sensor, which produces a signal representative of paper or film tension. The paper or film tension signal is used to selectively couple one signal from a number of sources of predetermined different frequencies to the motor to control its speed in accordance with the sensed paper tension.

摘要： A motor speed control system comprises an encoder (12) which produces a series of indicator pulses related to the motor's speed. The period of the pulse is compared with that of a crystal-controlled reference period produced by a period generator (14). Comparison is made by means of a period comparator (16) consisting of logic elements, including flip-flops (F1, F2, F3) and gates (G1 and G2). Digital outputs of the period comparator control UP and DOWN charge pumps whose integrated value controls the motor through a power driver. Advantages of the system are precise digital control with crystal accuracy.
