PIDFeedforward

is an option to PIDTune that controls the reference weights used for the feedforward filter.

Details

For a PID controller , the feedforward weights and affect what fraction of the reference signal to feed the proportional and derivative terms of the controller.
Possible settings include:

	None	{1,1}; use no weights
	Automatic	automatically compute weights
	b	{b,1}; set the proportional weight
	{b,c}	set proportional and derivative weights

Examples

Specify the reference weights of the feedforward filter and extract the filter transfer function:

Wolfram Language code: lsys = TransferFunctionModel[{{{1.}}, 2 + 3*s + s^2}, s];

Wolfram Language code: PIDTune[lsys, "PID", "Feedforward", PIDFeedforward -> {0.6, 0.9}]

Set only the proportional weight:

Wolfram Language code: PIDTune[lsys, "PID", "Feedforward", PIDFeedforward -> 0.8]

The automatically computed proportional weight:

Wolfram Language code: PIDTune[lsys, "PID", "FeedforwardParameters", PIDFeedforward -> Automatic]//First
