Whenever you deploy a trigger/ class from sandbox to production, you need to make sure you have a test class for each (also the code coverage should be greater than or equal to 75%). So since you are trying to deploy a controller (which in turn is a class), you need to create a test class. You can google search to know what is test class and code coverage.

The classes in the changeset must have a code coverage of 75% or more.
Add their test classes as well and enter the test class names in a comma separated list in the run specified tests box.
