Practical verification of adaptive dynamic matrix control with interpolated parameters

The paper presents the experimental studies of the adaptive dynamic matrix control (DMC) algorithm with interpolated parameters. The idea of adaptation mechanism is to determine the controller parameters that appear in the control law equation for several operating points of the system. In turn, the parameter values between the two consecutive operating points are calculated by using linear spline interpolation. The effectiveness of the adaptive DMC algorithm is studied for the electric flow heater for various number of operating points (interpolation nodes) in the presence of step changes in the set point and mean power of the electric heater. The obtained results show that it is possible to significantly reduce the number of interpolation nodes, while keeping the control system performance at a satisfactory level.
