英文摘要	In order to solve the delay in the optoelectronic tracking system, some scholars have proposed the PID-I controllerbased on the traditional PID controller. PID-I controller is formed by connecting an integrator in series to improve the system performance of the CCD position closed loop. But how to choose controller parameters is a key factor in determining system performance. The open-loop gain and bandwidth of the system are two important indicators for selecting the controller parameters, but these two indicators are coupled and cannot achieve the optimal performance at the same time. Meanwhilethe multidimensionality of the controller parameters also makes it difficult to set the parameters. In view of the above problems, traditional numerical methods and artificial experience methods cannot obtain good controller parameters. Therefore, this paper uses the NSGA-II multi-objective optimization algorithm to optimize the open-loop gain and bandwidth of the system at the same time by a non-inferior ranking method to achieve the purpose of optimizing the controller parameters. The theory and simulation show that the performance of the optoelectronic tracking system using this multi-objective optimized PID-I controller is better than that of the PID-I controller optimized by numerical methods in closed-loop bandwidth and step response indicators. © 2020 IOP Publishing Ltd.
