1. A method for controlling the operation of an isolation system having a damper assembly interconnecting relatively movable members to attenuate the transmission o forces therebetween in which the relative movement of the members in at least one direction is restricted beyond a certain limit by an end stop, said method comprising the steps of:

  • monitoring conditions of operation of said isolation system and producing data indicative thereof;

    providing damper command signals to said damper assembly to adjust the damping characteristics thereof in accordance with preselected primary control instructions and as determined by said data;

    altering said damper command signals provided to said damper assembly as determined in accordance with preselected override control instructions in order to change said damping characteristics at times when said system under control of said damper command signals alone will meet or exceed said end stop, thereby minimizing end-stop collisions.
