Optimization of Building Construction Control System Based on Nonlinear Image Enhancement

Abstract
To reflect the nonlinear characteristics of the building structural \r\nadjustment system, an active vibration control strategy based on the nonlinear is \r\nproposed. In this method, the size of the structural control force is determined by \r\ncomparing the allowable energy with the actual energy, and its direction is \r\ndetermined by taking the derivative of the energy. Because there is no need to \r\nsolve the linear matrix inequality, the calculation is simple and the operation is \r\nconvenient. Moreover, when multiple actuators with the same capacity limit are \r\nused, the control output force is consistent, thus avoiding the design of multiple \r\ncontrol systems and simplifying the controller design. The simulation results show \r\nthat the maximum controlled displacements of floor 6 to floor 8 are 1.16cm, \r\n1.12cm, and 0.97cm, respectively. The proposed nonlinear energy control method \r\nhas the advantages of simple control process and avoiding actuator saturation.
