The magnet power supply of the accelerator is an important part of this proj ect.In this design,the magnet power supply of accelerator is taken as the control obj ect,and the design of LQR controller of magnet power supply is proposed based on PSO.The state-space model of the magnet power supply is established,then PSO algorithm is used for the weight matrices optimiza-tion of LQR controller in order to ensure that the magnet power supply can quickly provide a magnetic field required by the heavy ion accelerator.The experimental results indicate that the method can meet the requirements of fast response of the system’s output,and each control index is obviously superior to the traditional method for LQR control.
