A multi-time-delay compensation controller using a Takagi - Sugeno fuzzy neural network method for high-rise buildings with an active mass damper/driver system

摘要

An active mass damper/driver (AMD) control system with a single mass has such problems as the excessive weight of the auxiliary mass and the insufficient capacity of its driving equipment. It is necessary to work through multiple subsystems to achieve effective control of high-rise buildings. However, the time-delay effect in each subsystem impedes its application in engineering practices. In the paper, an augmented system based on a zero-order hold is proposed for discrete-time systems with multiple time delays, and then the system is designed according to the compensation strategy using a classical linear quadratic regulator algorithm. After that, the sample data obtained from the zero-order hold compensation controller is trained through a Takagi-Sugeno fuzzy neural network method. Finally, a new simplified compensation controller is designed to further shorten the time consuming calculation on the premise of guaranteeing its control effects and parameters. To verify its effectiveness, an AMD system in a high-rise building is regarded as an example, and the proposed methodology is also applied to an experiment of a four-story frame. Both results demonstrate that the method can enhance the performance of an AMD system with multiple time delays.
