Title:
ELECTRIC ACTUATOR CONTROLLING DEVICE
Document Type and Number:
Japanese Patent JP3927434
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To optimize responses to any operation request by preventing overshoot in responding with actual manipulated variable when a value of a manipulated variable exceeds a prescribed line voltage, without sacrificing response with the actual controlled variable when the value of the line voltage is limitless in the electric actuator controlling device containing a integrator for feedback controlling of the electric actuator.
SOLUTION: An electric actuator drive controlling device comprises a comparing means C3 and an integral manipulation variable correcting means C4. The comparing means C3 compares a line voltage value VB and an absolute value &verbar V-1&verbar of the previous instruction for manipulation variable for driving the electric actuator 5. The integral manipulation variable correcting means C4 decreases the amount of integral manipulation variable IU for correction when the absolute value &verbar V-1&verbar of the previous instruction for manipulation variable is evaluated larger than the line voltage value VB by the comparative means C3.
