Implementing active force control to reduce vibration of a short length drive shaft

摘要: Vibration is a physical phenomenon involving repeated oscillatory movements or fluctuations at certain frequency and typically undesirable in many applications since it may cause undue failure damage to the system. In this paper, vibration of three degree-of-freedom (DOF) model representing short length drive shaft has been effectively robustly suppressed through implementation novel Active Force Control (AFC) used conjunction with classic proportional-integral-derivative (PID) controller. The caused by its support constraint during operation was simulated using MATLAB Simulink considering number operating loading conditions. results proved that when pure PID controller implemented, indeed reduced but expense longer execution time producing noticeable oscillation slight offset. On other hand, AFC loop engaged adding directly series (PID+AFC) produce 2 DOF without any need further tune gains, significantly amplitude hovering zero datum offset yielding an extremely low trending.
