The invention relates to a design method of linear motor PID controller based on attenuation curve method for an industrial robot, belonging to the technical field of linear motor of industrial robot.In the design, a mathematical model of the linear motor is built first, and then an entire simulated picture under the Simulink environment which in the version of MATLAB2014 is built. On this basis,the attenuation curve method is used to tune the parameters of the linear motor PID controller, if a response curve of the system is not good after simulation, fine tune the parameters on the basis by cut-and-try method. The design method of linear motor PID controller based on attenuation curve method has the advantages that: compared with tuning PID controller parameters by using traditional cut-and-try method, the method can reduce a large amount of time for tuning, be simple to operate, and the method can realize a best tuning of the parameters of the linear motor PID controller. Througha model simulation, the res
