What is the difference between split range and cascade control?

Cascade, override, and split range control.

Cascade control is widely used for minimizing the effects of certain types of disturbance in the process. On the other hand, override and split range controls are used for controlling certain types of multivariable processes.

For example

The split range can be considered as one transmitter that can control 2 Valve from 0% to 100% cascade can be described as it uses 2 Transmitter to control one valve.
