Interval RTD-A Control for Non-square Systems

Aiming at interval control of multi variable non-square systems, this paper proposes an interval predictive control algorithm for thin systems based on the RTD-A algorithm. The set interval is introduced into the optimization index and the control variable is obtained in real time based on gradient descent algorithm. By adjusting the weight to restrain the interference and reduce the energy consumption of the controller with small actions, the actual control output can be avoided from exceeding the expected range to the greatest extent. Simulation results show the effectiveness of the proposed algorithm.
