Yang Zhidong[4] employs root-locus method, with graphic mode, to describe all the six parameters’ numerical relationship of shaking table closed-loop system pole with feedforward and feedback, but practical system model is very different from theoretical model, and the calculation process is complicated and tedious, which often results in big deviation of the parameter obtained through this method. empirical tuning is concluded by engineering technicians through lots of practice and is based on existing experience.
