Active Disturbance Rejection Control simulation toolbox in open-source software Scilab/Xcos

To satisfy high accuracy and speed requirement, a kind of Active Disturbance Rejection Control (ADRC) solution is proposed according to the complexity of Monitor Finishing Automatic Width Control (FAWC) system with large time-delay for hot strip mill. In order to improve the versatility of ADRC parameters, a unit gain was added in the loop. Based on the simplified model, the presented ADRC consists of linear functions which make it easier to realize. For applying ADRC algorithms conveniently and widely, the control system is implemented in Scilab/Xcos, which is one of an Open-source Software for Scientific Computation (OSSC) and is free of charge. According to the program of data exchanging between Xocs and Scilab, Xcos simulation can be carried out in batch processing in Scilab. The disturbances rejection and robustness of the proposed control method is verified by ADRC simulation toolbox in Scilab/Xcos.
