Control of Electric Load Simulator Based on Fuzzy PID
An approach of dynamic emulation for mechanical loads is presented.The control strategy can emulate the static and dynamic characteristics of mechanical load.Load emulation system can be used for the validation and testing of the electrical drives and complex control algorithms.Actual mechanical loads is replaced by load emulation motor.The dynamic model of experimental platform is presented firstly,then the dynamic emulation approach of load emulation is derived detailedly.In this strategy,the torque demand of the load emulation motor is calculated from the closed-loop control algorithm.Experimental simulation results of the closed loop control of linear mechanical loads are presented based on Matlab/Simulink,which show the feasibility of the control algorithm,even if the rotational inertia of the experimental system differs greatly from that of the actual mechanical system.
