With an open loop system, the only way to modify the behaviour of the system is to modify the values of physical parameters in the system. For instance we can modify the damping coefficient of a damper. This can be done in vehicles for instance. By modifying the dampers, the coefficient C can be changed to modify the behaviour of the suspension in order to yield a desired behaviour. A high damping ratio will be used to yield a better road-holding quality at the expense of the comfort of the driver and passengers (e.g. old Corvette models before semi-active suspension systems were introduced). A low damping ratio will yield a better comfort at the expense of the road-holding quality (e.g. most Cadillacs). This is the classic compromise between vehicle stability and ride comfort for passive suspensions.
