An integrated process for the control, centering and regulation of the camber of a metallic strip in process lines wherein the strip is passed over a centering group comprising a mobile frame carrying one or more rolls and which operates a rotation (β) with respect to a fixed supporting frame effecting a shift of a branch of the out-going strip with respect to a branch of the in-going strip, wherein the rotation (β) of the mobile frame takes place around an axis tilted with respect to the plane on which the in-going branch of the strip lies, which creates a steering angle (γ) of the roll axis with respect to the perpendicular to the axis of the line by a rotation of a tilt angle (α) of the frames with respect to the plane perpendicular to the in-going branch, wherein sensors (15, 16, 17) are positioned on the strip arranged along the line and connected to an electronic control board which receives the data of the advancing strip (position and camber) and, on the basis of a control algorithm, used by the controller which has the following form: - for the correction of the proportional part in β: Up = Kp * Ep wherein Up is the intervention to be effected on β for the correction, Ep expresses the positioning error of the strip (as revealed by the sensors) and Kp is a dimensional parameter which expresses the gain and offset reading; - for the integral part in α Ui = Ki * Ei wherein Ui is the intervention to be effected on α for the correction, Ei expresses the camber error of the strip (as revealed by the sensors) and Ki is a dimensional parameter which englobes the gain and translation to α of the curvature parameters revealed; - wherein for a given positioning error Ep = e, a Up is generated on β, equal to the entire total correction predicted, i.e.: Up = e * Kp - and wherein there is a camber error Ei = e' with which the integral correction (steering γ) must be calculated, which is calculated and established through the actual tilt α and β; the gain being regulated to be lower than 1 (complete correction of the camber) using, for example, the "Ziegler-Nichols" method, 50% of the total correction intervention is adopted, i. e.: Ui = e ′ * Ki / 2 wherein said algorithm calculates the correction interventions, acts on the actuators (22, 23) connected to said fixed frame and mobile frame and, in the case of a line with thermal sections, acts on cooling areas of the strip downstream of the hot section of an oven. - for the correction of the proportional part in β: Up = Kp * Ep wherein Up is the intervention to be effected on β for the correction, Ep expresses the positioning error of the strip (as revealed by the sensors) and Kp is a dimensional parameter which expresses the gain and offset reading; - for the integral part in α Ui = Ki * Ei wherein Ui is the intervention to be effected on α for the correction, Ei expresses the camber error of the strip (as revealed by the sensors) and Ki is a dimensional parameter which englobes the gain and translation to α of the curvature parameters revealed; - wherein for a given positioning error Ep = e, a Up is generated on β, equal to the entire total correction predicted, i.e.: Up = e * Kp - and wherein there is a camber error Ei = e' with which the integral correction (steering γ) must be calculated, which is calculated and established through the actual tilt α and β; the gain being regulated to be lower than 1 (complete correction of the camber) using, for example, the "Ziegler-Nichols" method, 50% of the total correction intervention is adopted, i. e.: Ui = e ′ * Ki / 2 wherein said algorithm calculates the correction interventions, acts on the actuators (22, 23) connected to said fixed frame and mobile frame and, in the case of a line with thermal sections, acts on cooling areas of the strip downstream of the hot section of an oven.
