Research on Synchronization Control Strategy of Dual Drive Feed System by Using Single Neuron PID

Dual drive feed system (DDFS) has the characteristics of high stiffness and high precision, and has been widely used in automation equipment. It is difficult to control some complex and nonlinear processes effectively under the traditional control strategy of dual drive feed system, which results in unsatisfactory synchronization performance. So, it is of great significance to study the synchronous control technology of DDFS to improve the synchronous performance of DDFS. Considering that the DDFS is a complex electromechanical coupling system, the mechanical rigid-flexible coupling dynamics model of the DDFS is established in this paper. A synchronization control strategy based on single neuron PID (SN-PID) is proposed, and the synchronization errors of different control strategies are considered through the simulation analysis of the model. Experimental results show that the SN-PID synchronous control strategy has better synchronization performance than the traditional cross-coupling control strategy. It provides a certain basis for the optimization of the subsequent synchronous control algorithm.
