Embodiment Construction

[0056] Now refer to the attached picture: figure 1 The actuator and sensor responses for the automated sensor calibration process are demonstrated. A series of actuator ramps (4) were performed (cycles of any length could be used, but a 1 minute cycle was used as an example), and the sensor response was recorded (3). figure 1 Three ramps are shown, although any number of ramps can be used for the process. The purpose of the calibration process is to determine the maximum (1) and minimum (2) sensor levels. The maximum (1) and minimum (2) values ​​can be mathematical formulas, such as the integration of the highest or lowest value over a suitable period of time, or as an average. These values ​​are automatically recognized and recorded, for example, by scaling the sensor curve so that the maximum value (1) is represented as 100% and the minimum value (2) as 0%. The actuator values ​​corresponding to the maximum and minimum sensor values ​​are points (5) and (6) - the operatin...

Abstract

The present invention relates to feedback control for automatic tuning and calibration systems and processes. According to the invention, a series of actuator pulses is carried out automatically, and based on the slope of the sensor's response, the dynamic information of the system to be controlled is determined (this will be called the system identification process). This is done through an automated sensor calibration process to determine the controller's operating window. Based on the information collected during system identification, the parameters of the controller for the specified time for the sensor to reach the set point are automatically calculated. The present invention relates to any system managed and / or controlled by a controller and / or control algorithm. The present invention relates to parameterizing any control algorithm like PID, PI, P, PDF using the method of the present invention.

Description

technical field [0001] The present invention relates to improvements in feedback control, in particular, but not limited to, feedback control of systems and processes. Embodiments of the invention also relate to the calibration and parameterization of control systems for such applications, and / or to the identification of system and process dynamics. Background technique [0002] Control systems are often used to regulate and control systems and processes. Control systems typically include sensors and actuators whereby inputs to the actuators result in changes that are detected by the sensors. In almost all cases, those skilled in the art will understand that there is a non-linear relationship between the input of the actuator and the output of the sensor, which may be due to, for example, the speed of the actuator, the responsiveness and resolution of the sensor, the time lag , mechanics, inertia, and a wide range of system variables. [0003] As such, almost all control ...
