Popis: The paper proposed a controller combined fuzzy logic with linear quadratic regulator (LQR). This controller was able to adjust the swing angle precisely during the lifting of gantry crane. It resolved the problem that the LQR controller mostly depending on the accuracy of the mathematical model. First, the paper analyzed the design method of the LQR, then an improved method combing with fuzzy logic was put forward in detail and a further simulation experiment was carried on the MATLAB. The result shows that compared with LQR, the Fuzzy-LQR method can drive the crane to destination in a shorter time and reduced the swing angle by a third.
