Abstract: A segmented mirror control system (10) is presented wherein an array of structural elements (e.g. mirrors) (10) can be actively positioned to maintain an accurate pre-determined overall shape. The present invention is "active" and so may be characterized as an Active Segmented Mirror Control "ASMC". The segments of a mirror or the reflecting panels, in for example, a radiotelescope, may be continually adjusted with ASMC to provide an accurate reflecting mirror of very large diameter even when disturbed by external forces. ASMC is a closed loop control system. That is, an array of sensors (16) is first used to measure differential position errors. This data is then processed to determine position actuator (14) commands. Finally, these commands are used to move the segments until the sensors are nulled and the desired shape is obtained.

Abstract: A control system of a servo circuit having a speed control unit (13) for controlling the speed of a servo object (11); a position control unit (14) for controlling the position of the servo object (11); a switching unit (15) for switching the connections of the servo object (11) between the speed control unit (13) and the position control unit (14); a main control unit (16); and optionally a speed zero detection circuit (39, Figure 12A) which compares the real speed (Vr) and a slice level and detects if the real speed (Vr) is less than a fixed value. A method for speed control of such a system includes a step of producing a target speed using an amount of movement X in an amount of required movement d as a remaining amount of movement and a step of producing, after producing a target speed for movement by the amount of movement X, a target speed of equal speed for the remaining amount of movement Y (Fig 3B). A method for controlling the switching of the position control of the servo circuit in such a system includes a step wherein the main processing unit (16) judges if the conditions for switching to the position control exist during the speed control; a step of monitoring the conditions for switching for a fixed time X after detection of the existence of the switching conditions; a step of switching to the position control in accordance with the existence of the switching conditions for the fixed time X; and a step of returning the to the step of judgement of the switching conditions if they collapse within the fixed time. Another method of control in such a system comprises producing and outputting a target speed using an amount of movement (X) in a total amount   of movement (d) as a remaining amount of movement, producing and outputting a target speed of an equal speed of the remaining amount of movement Y, and switching the value of the slice (SLl) level in the speed zero detector circuit (39) movement (X) and after the movement (Y).

Abstract: An image forming apparatus has the rotation of a fixing roller (14) controlled, said fixing roller being drivable by first and second motors (1,2), the first motor being driven at a higher speed than the second motor. The torques of the first and second motors are transmitted to a rotary shaft of the fixing roller through respective one-way clutches (7,8). The drive of the second motor is started immediately before the driving of the first motor is stopped at the end of an operation of the apparatus, and the drive of the second motor is maintained at least until the drive of the first motor is restarted. The continued low speed rotation of the fixing roller prevents it adhering to its backing or presser roller between operations.
