A concept for semi‐active vibration control with a serial‐stiffness‐switch‐system based on vibration energy harvesting was previously presented. This contribution investigates a variable structure control‐based switching law to reduce the settling time of the system response under a nonzero velocity initial condition. The proposed switching law is able to fasten the transformation of initial vibration energy of the system into potential energy stored equally in its two springs. It is characterized, simulated, and proven to be more effective than the old switching law.
