摘要：

In this research, new toggled actuator forces were proposed. For this purpose, numerical and experimental investigation of the installation of the actuator in a toggle configuration for the decreasing of active control forces in engineering structures has been carried out. In the first part, numerical studies were investigated. In addition to numerical research on the effects of the toggle configuration on actuator forces, an experimental investigation has been carried out by building a table model of the mentioned system. The algorithm of the system is LQR, and ATmega328 has been used as a control platform. Comparing results through the experimental and numerical processes express high matching that relies on mitigating control forces in the toggled active model. Based on the results, a significant reduction in actuator forces through using the proposed toggle configuration.
