SUMMARYA new semi-active control strategy that approximates a predicted control output of a reference active control is proposed. A variable parameter of a semi-active control device is selected at every time instant so that the predicted control output of the semi-active control system becomes close to the corresponding predicted control output of the reference active control as much as possible. Parameters of the reference active control law are optimized in the premise of the aforementioned 'output emulation' strategy so that the control performance of the semi-active control becomes good and the 'error' in the sense of achieved control performance between the reference active control and semi-active control systems becomes small. A pole placement method based on a linear matrix inequality (LMI) framework is adopted as the reference active control law. Parameters to determine the domain in the complex plane where the closed-loop poles are placed are searched so that control performance of the semi-active control system based on the output emulation approach is optimized.

Cooperative Control Method of Active and Semiactive Control: New Framework for Vibration Control

A new control design framework for vibration control, the cooperative control of active and semiactive control, is proposed in the paper. In the cooperative control, a structural system having both of an actuator and a semiactive control device, for example, MR damper and so forth, is defined as the control object. In the proposed control approach, the higher control performance is aimed by the cooperative control between the active control with the actuator and the semiactive control with the semiactive control device. A design method to determine the active control input and the command signal to drive the semiactive control device based on the one-step prediction of the control output is proposed. A simulation example of a control system design for a benchmark building is presented to show the effectiveness of the proposed control framework.

Active/semi-active hybrid control for motion and vibration control of mechanical and structural systems

As a new control design framework for motion and vibration control of mechanical and structural systems, an active/semi-active hybrid control (ASHC) methodology is proposed in this paper. In the proposed ASHC framework, a mechanical system that has both an actuator for motion and vibration control, and a semi-active control device, e.g., MR damper, for vibration control is defined as a control configuration. Depending on the location of the actuator and the semi-active device, two ASHC problems are formulated as optimization problems of the control performance on the motion and vibration control. In the ASHC approach, the higher control performance is accomplished by the cooperative and complementary control of the actuator and the semi-active control device. Some solution candidates and design examples are presented to show the effectiveness and the importance of the ASHC framework.
