The DLS employs multiple actuators to simulate dynamic loading environments such as wind, wave and earthquake effects and may be used as an alternative to conventional facilities such as wind tunnels, wave tanks and shaking tables. Control of multiple-actuators is difficult due to the inherent problem of cross-coupling, which implies that each actuator affects the dynamics of other outputs. In order to compensate for these interactions, a new type of coupled control system using the nonlinear control system toolbox in MATLABTM has been developed in this study. This technique solves the time-domain control parameter-tuning problem as a constrained optimization problem. An application of the DLS system for applying simulated wind loading utilizing two-point correlated signals is presented in this paper. The simulated loading time histories match the target values with high fidelity.
