Research of Three-Variable Control Parameter Tuning Technology on Seismic Simulating Shaking Tables

A fast three-variable parameter tuning method was presented through the research on three-variable control (TVC) and its parameter tuning technology on seismic simulating shaking tables. The research on three-variable control algorithm derived the arithmetic expressions of parameters in three-variable feedback and feedforward loops, and completed the parameter tuning of the three-variable controller, which greatly improved the efficiency of three-variable parameter tuning process on seismic simulating shaking tables. Finally, simulation and field tests by the traditional three-variable control parameter tuning method and the fast three-variable control parameter tuning method further showed the feasibility and high efficiency of the fast three-variable control parameter tuning method.
