measuring the input variables of the process by placing the sensor at the input end of the system and modelising the potential output data

feedback, feedforward and cascade sytems working together

outputs that get changed as a result of process control

you have to wait for something to go wrong before you can correct it

electronic readings from sensors

the difference between what the input parameters should be in feedforward control, and what they really are

you have to find an accurate model to modelise your system first

aspects of the system that process control looks at

the sensor is placed at the output end of the system, it sends data back to the controller

in a feedback system, the difference between the observed output and the setpoint

the number that represents the target output or operating state that you want a process to achieve

added to feedforward and feedback control with more sensors to provide more data

I __________ gone to the cinema yesterday, but instead I visited my Grandma.

You __________ finished already - you only started 3 minutes ago!

You __________ come - the meeting has been cancelled.

Have you seen Peter? His car has gone so he __________ left.

She doesn't know Ann,

You've got a camera,

Kate won't be late,

Kate's applied for the job,

Jack's on holiday,

You're tired,

You can speak German,

You weren't listening,
