An active vibration isolative technique based on the giant magnetostrictive actuator was proposed, and a two-stage imitative vibration isolative platform for precise instruments was developed. Based on the imitative vibration isolative platform, the mathematical models of the system were established. According to the immune theory, an immune PID controller was designed to match the vibration active isolation system. Finally, this active control system of imitative vibration isolative platform was simulated using Simulink software and tested in the laboratory. The research results demonstrate that it can effectively suppress environmental vibration and satisfy vibration isolative requests of general precision instrument.
