Traditionally, the shaking table tests are controlled using linear controllers, which are designed to regulate linear systems. With the nonlinearity within the actuator and the specimen tested to highly nonlinear states, the traditional linear controller can no longer control the shaking table accurately. This paper focuses on the theory and implementation of a nonlinear algorithm, Sliding Mode Control (SMC), to regulate shaking table tests and compared its response to the traditional PID controller. The result shows that the proposed algorithm was able to provide excellent tracking for the shaking table testing, even when the specimen reached highly nonlinear states. This provides the needed demonstration to show that the proposed SMC controller is a viable and robust control algorithm to regulate the shaking table to test nonlinear systems. © 2013 Earthquake Engineering Research Institute.
