摘要
The invention relates to a method for the closed-loop control of a proportional integral-type controller (2) in an instrumentation and control device (1) of a closed-loop control system (3), in particular a servovalve-actuator system, said controller (2) including a setpoint-weighting coefficient (β), said closed-loop control method comprising the consecutive steps of assigning (11) a unit value to the set-point weighting coefficient (β), optimizing (12) a closed-loop control of the controller (2) satisfying at least one predefined performance criterion, defining a characteristic tracking error (εTC) making it possible to respond to the performance constraints of the system to be closed-loop controlled, and assigning (132) a setpoint weighting coefficient (β) value, depending on the characteristic tracking error (εTC) and the closed-loop control of the controller (2).
