Q. Feed-forward control - prevention rather than cure?

Feed-forward control would be a system that in a pre-emptive way, reacts to changes in its environment, normally to maintain some kind of desired state.   Feed-forward control systems react to future performance expected e.g. make control adjustments, before adverse conditions expected do occur. 

• Forecasting ahead and doing something now before the event occurs
• Examples include cash budgeting or strategic planning
• Control action would be 'closing the stable door before the horse bolts'
