Which claim is correct? A transfer function model for a stable process always has no time-delay. Feedforward control can be solely used for the setpoint tracking If a process has 3 inputs and 3 outputs, then we need to build 6 transfer function models for it. The inner loop of cascade control has to be slower than the outer loop No correct answer
