Dalek Controller

The Dalek Controller is a rank in the Daleks in which the Dalek designated as Controller is in charge of a major Dalek operation.

In 1930 when the Cult of Skaro created an army of Dalek-Humans in New York City on Earth, Dalek Caan was designated Dalek Controller, becoming linked with and taking control of the new army.(DW: Evolution of the Daleks)

As Controller, Caan became connected with the Cult's military computer, which may lead the Dalek Controllers and the Dalek battle computers to have some connection.

The Daleks, having conquered Earth in alternate timeline, used a Controller as their collaborator.(DW: Day of the Daleks)

The Controller of the Game Station in 200,100, though not a Dalek herself, was under their control, making sure any contestants that lost were transported to the Daleks to become Daleks.(DW: Bad Wolf)

Dalek Controllers were not of a high authority, where as the Cyber-Controllers were the supreme leaders of the Cybermen.
