Smith Predictor-Taylor Series-Based LQG Control for Time Delay Compensation of Vehicle Semiactive Suspension

الملخص EN

A Smith predictor-Taylor series-based LQG (STLQG) control to compensate time delay of a semiactive suspension system is newly presented.

This control consists of a Taylor series-based LQG (TLQG) control and a Smith predictor based on the TLQG.

The TLQG control compensates one half of time delay to decrease magnification from whole time delay compensation.

The Smith predictor based on the TLQG compensates the other half to decrease horizontal shift from whole time delay compensation using the Smith predictor-based LQG.

Finally, a practical case illustrates advantages of the STLQG control.
