You're not asking a sensible question. These are features or choices in the way a controller is implemented. Whether or not you need them depends on the system you are trying to control. For example, gain scheduling refers to the idea of changing PID gains as the setpoint or another condition changes. This is not often necessary, but is useful when your system can operate in distinct ranges that have different performance characteristics. Bumpless transfer means you can go from manual operation to PID control without any sudden change in output. Integrator anti-windup limits the effect of integral control to avoid a large overshoot when making a step in setpoint. Ramping the setpoint is another way to avoid integral windup.
