Abstract
Described herein are techniques and systems for online ad campaign tuning using proportional-integral-derivative (PID) controllers, such as proportional (P) controllers and proportional-integral (PI) controllers. Also, described herein are techniques and systems for shortening a learning/tuning phase of a PID controller used for optimizing an online ad campaign.
Claims20
A system stored in a storage device executable by a processor, comprising:
- controller interface circuitry configured to:
- receive a measured process variable of an online ad campaign, a respective goal variable, and a proportional gain coefficient;
- and
- determine an error variable according to the measured process variable and the goal variable;
- and
- controller circuitry configured to:
- receive the error variable;
- and
- calculating pricing of the online ad campaign according to the error variable, wherein the calculating includes:
- a determination of a controlled input variable according to the error variable and the proportional gain coefficient;
- and
- a communication of the controlled input variable to adjust the pricing of the online ad campaign.

A method, comprising:
- setting a set point for controlling pricing of an online ad campaign, by controller interface circuitry;
- setting a plurality of goal points of an equilibrium surface for controlling the pricing of the online ad campaign, by the controller interface circuitry;
- directing, by controller circuitry communicatively coupled to the controller interface circuitry, a parameter of the online ad campaign towards the set point;
- and
- where the direction of the parameter towards the set point results in the online ad campaign being marginally stable or unstable, redirecting the parameter towards the equilibrium surface.
