摘要： A tracking servo system for controlling the positional difference between a recording track of an optical disk and a light beam emitted on the track, in which the amount of offset control applied to an offset adjusting amplifier provided in the servo loop is varied and the center value of the positive and negative peak values of a track error signal obtained at that time is computed. Then, the relation between the amount of offset control and the center value of the peak values of the track error signal is determined and the amount of offset control corresponding to the desired center value of the peak values of the track error signal is obtained on the basis of the determined relation. Further, a laser beam emission power adjusting system used for recording and/or reproducing in an optical disk apparatus is disclosed, in which the laser beam emission adjusting output is varied and the amount of beam emission power obtained at that time is detected. Then, the relation between the laser beam emission adjusting output and the amount of beam emission power is determined and the value of the laser beam emission adjusting output corresponding to the desired amount of beam emission power is obtained on the basis of the determined relation.

摘要： A method of controlling automatic state returns relates to a dynamic system coupled to an automatic control operating in a discrete negative feedback mode. The method includes a phase for defining a controller, and a phase for operating the system. The defining phase is realized in an open-loop learning phase which includes a step of reading states in which a system may be situated, and a step of generating commands for returning the system to an ideal state. When the commands generating step takes place, the method supplies, for each state, a sequence of discrete commands which are determined by imposing a constraint intended to reduce the error relative to that state below a predetermined threshold.

摘要： A valve position controller tuning method avoids impact of friction in valve positioner tuning by building a dynamic model of a valve positioner from a monotonic open-loop response of a valve stem position to a change in valve position controller output. To this end, a model form is selected based on the type of pneumatic actuator and relay that controls valve flow modulating of member motion, and the valve position controller is operated in an open-loop mode. The method includes changing a valve position controller output signal to cause the valve positioner to move a valve flow modulating member, connected to valve positioner, monotonically from one stuck position to another stuck position immediately after a motion in that same direction. When a valve stem position reaches a position threshold, a first valve stem position change and a corresponding time change are measured. The method includes measuring valve stem position changes at times that depend on the first measured time change. Using the measured results, valve positioner response parameters are calculated for the selected model form from which valve position controller tuning constants are calculated.
