Abstract
In this paper, we have investigated the performance of Iterative Linear Quadratic Regulator (ILQR) on trolley position of 3DOF crane. In ILQR, we select optimum parameters Q and R automatically instead of hit and trial method. Algorithm chooses the parameters Q and R which results in minimum trolley’s settling time of the jib system. A number of simulations have carried out using Matlab/Simulink. The results show that the optimized LQR results reduce settling time of trolley along with smaller overshoot with less rise time.
