Title:
AUTOMATIC CONTROLLER AND ACTUATOR DRIVING DEVICE
Document Type and Number:
Japanese Patent JP3216658
Kind Code:
B2
Abstract:
PURPOSE: To sufficiently suppress the dynamic deviation by detecting a disturbance component from inputted data to generate an operation center signal changed in accordance with the disturbance.
CONSTITUTION: An input signal I from an input terminal 1 is outputted to a subtractor 2, and a part of an output signal O from an output terminal 7 is fed back to the subtractor 2. The subtractor 2 subtracts the output signal O from the input signal I and outputs the result to an adder 3. The adder 3 adds the output from the subtractor 2 and a disturbance N (t) from an input terminal 4 and outputs the result to an adder 5. The adder 5 adds the signal inputted from a D/A converter 11 and the output of the adder 3 and outputs the result to a gain controlled amplifier 6. This amplifier 6 multiplies the output signal from the adder 5 by a gain G and outputs the output signal O. A part of the error signal from the sub-tractor 2 is multiplied in a gain controlled amplifier 8 by a gain C+1 and is converted by an A/D converter 9, and data is operated by a CPU 10 and is outputted as data which sets the operation center of automatic control.
