This paper presents a horizontal active vibration isolator (HAVI) using both horizontal and vertical forces of an electromagnetic planar actuator (EPA). The horizontal force is used to reject horizontal disturbance while the vertical force is applied to adjust natural frequency of the HAVI. A simulation model of the active horizontal isolator with flexible beam column (FBC) is built and active isolation methodology using both horizontal and vertical forces of the EPA is implemented. Simulations and experiments show that PID gain of the HAVI is tuned properly so that the horizontal vibration due to impulse disturbance is reduced by 90%. In addition, vertical force of the EPA can reduce the natural frequency by 40% for improving its ground isolation performance, compared to horizontal force only.
