Abstract

In the single-excitation-motor inertial flip-flow screen, the vibration phase difference is difficult to maintain at the ideal angle of 180° for two screen frames, which results in the low screening efficiency. To solve this problem, a flip-flow screen driven by double excitation motors is established, together with its control system. The vibration phase difference for two screen frames can reach 180° when the phase difference for two eccentric blocks is 170° based on the experimental model. Therefore, the speed synchronization based on cross-coupling and improved point-based Bang-Bang phase compensation control strategies are proposed and dSPACE is used to build the control platform. Experimental results achieved have been confirmed the control effectiveness during screening process.

Keywords: Inertial flip-flow screen; Phase compensation; Speed synchronization; Vibration phase difference; dSPACE control platform.
