Parameter identification of energy consumption dynamic model for double‑motor‑driven belt conveyers based on Actor–Critic framework

Research on the energy consumption model of belt conveyors is of great significance when it comes to reducing energy consumption. When compared with a conveyor driven by a single DC motor, the energy consumption model of a conveyor driven by dual motors and its parameter identifications are more complicated. Thus, a data-driven method called Actor–Critic is integrated into the analytical expression method to build an energy consumption model and to estimate the parameters for belt conveyors driven by dual motors. In accordance with the measured current, speed, and capacity, three significant components in the Actor–Critic method, namely action, observation, and reward, are, respectively, designed to estimate parameters without model error disturbance or state operation. Results from experimental studies demonstrate the accuracy and robustness of the proposed method.
