Negative velocity feedback control

A constant gain matrix [G] is used to couple the input actuator voltage vector and the output sensor voltage as

	(21.20)

As stated above

	(21.21)

Substituting Equation (21.9) into Equation (21.10) yields

	(21.22)

Substituting Equation (21.11) into Equation (20.3), the equation of motion may be obtained

	(21.23)

is the active damping matrix
