Title: Backlash correction system for numerical controller
Inventor: FUJITA JUN
IPC: G05B19/18
Filed: 1989-12-28
Abstract: PURPOSE:To remove a projection phenomenon to be generated at the time of switching a quadrant and to attain high accurate correction by correcting backlash at the time of checking the stop of a motor or the inversion of a rotating direction after deciding the inversion of a moving direction commanded to a servo system. CONSTITUTION:A backlash correction time deciding part 35 decides whether a command moving direction inputted from a command moving direction storing part 25 is positive, zero, or negative, and at the time of a positive direction, decides whether a moving direction stored in an old command moving direction storing part 31 is positive or negative. Since the negative direction means the inversion of the moving direction from negative to positive, the deciding part 35 decides whether a speed positive/negative code inputted from a feedback speed storing part 33 is zero or positive. When the speed is zero or positive, the deciding part 35 commands a backlash correction variable output part 29 to output positive direction backlash correction. Since the positive moving direction means the inversion from positive to negative, the deciding part 35 decides whether the speed code obtained from the storage part 33 is zero or negative, and when the code is zero or negative, commands the output part 29 to output negative backlash correction.

IPC: F02D45/00
Filed: 1989-12-28
Abstract: PURPOSE:To prevent the air-fuel ratio from becoming still richer by making an air-fuel ratio controlling arrangement where a lower limit value guard is set on the fuel injection pulse width, and therein restricting the zero-reset of the feedback correcting amount made by a feedback stopping means during implementation of the lower limit value guard when the air-fuel ratio is in rich side. CONSTITUTION:While an engine is in operation, a control unit 25 reads the outputs of various sensors and determines the fundamental injection amount Te corresponding to the engine operating condition. Then the fundamental injection amount Te is compared with the specified lower limit value Temin, and if Te<Temin, the specified lower limit value Temin is set as the value of Te in order to set the lower limit value guard. Then a judgement is made whether the air-fuel ratio is rich on the basis of the output of an O2 sensor 18, and if yes and when the value pertaining to the output of O2 sensor 18 does not continue to change for a certain period of time, the judgement is made that the air-fuel ratio is abnormal. In this case the feedback correction amount is reset to zero and feedback control is stopped. But the resetting to zero is restricted as long as the lower limit value guard is being implemented.
