Exploitation of state-coupling, disturbance, and nonlinearities for suspension system control

A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor facilitate performance of operations, comprising:

• employing nonlinear dynamics for nonlinearly suppressing vibration of an active suspension system and to generate an ideal output tracking trajectory of the active suspension system;
• generating both disturbance and state-coupling effect indicators for the active suspension system;
• relating the disturbance and state-coupling effect indicators to one or more effects of the disturbance and state-coupling effect indicators on the active suspension system, where the disturbance and state-coupling effect indicators have not been eliminated via control of the active suspension system;
• and
• controlling the active suspension system based on the nonlinear dynamics and based on the disturbance and state-coupling effect indicators.

A method, comprising:

• employing, by a system comprising a processor, nonlinear dynamics usable to nonlinearly suppress vibration of an active suspension system;
• analyzing, by the system, a state-coupling effect of the active suspension system by relating amplitude and directionality, of disturbances to the active suspension system, to a tracking control cooperating with the active suspension system;
• and
• controlling, by the system, the active suspension system to thereby suppress the vibration of the active suspension system, based on the nonlinear dynamics and a non-cancelled state-coupling term that is output from the state-coupling effect analysis.
