Robust Controller Design for Network-based PMSM Servo Systems with Transmission Delay

【摘要】：正In industry applications,the remote Permanent Magnet Synchronous Motor(PMSM) can close its control loop via a digital network to reduce the cost and simplify the installation.However,the uncertain network-induced delay could degrade its performance.Considering the detrimental effects of delays in the communication network,we establish the model of Network-based PMSM servo system.Then sufficient conditions for the stability of the system is given.Based on these conditions,we propose a method to design a stable state feedback controller,which is robust against the transmission delay.Simulations were done to verify the correctness and effectiveness of the proposed controller design method.
