Abstract:

In order to optimize the cooperation and working accuracy of the internal motor assembly of the safety retractor of high bench cables used in open pit mines under a disturbed environment, a three-motor deviation coupling control method was proposed for the retractor. Firstly, a PI controller parameter setting model based on the SOA was constructed, with the ITEA as the objective function. Subsequently, the proposed method was compared with various algorithms by using three test functions, including Schaffer. Finally, three simulation models of permanent magnet synchronous motors (PMSMs) were built using MATLAB/Simulink, and the parameters were optimized through algorithms. The results show that the three-motor deviation coupling control method optimized by the SOA enables the motor assembly's speed to rapidly reach the set value with excellent stability. Moreover, even when disturbances are introduced, the motor assembly still exhibits good tracking and anti-interference capabilities. Additionally, this approach boasts advantages such as rapid convergence and lower error rates, providing robust support for the design and optimization of the safety retractor of high bench cables used in open pit mines.
