Function Documentation

qos_rv pid_init	(	void *	self,
		void *	self_params
	)

Initialize a Proportional-Integral-Derivative controller.

qos_rv pid_set_defaults

(

)

Configures a Proportional-Integral-Derivative controller with default parameters.

Tells to the QoS library to use a PID controller with a default set of parameters (null target scheduling error).
