Control Theory. D action – Time delays. Derivative Action. When there’s too much oscillation , this can sometimes be solved by adding a derivative action. This action will take into account how fast the error signal is changing . In the time domain this leads to :

Control Theory. Session 6 – Transfer Functions. Standard form of first order TF. We will consider changes w ith respect to a given initial equilibrium . Step response:. Step response of. Δ z (t). A. t. B.

CONTROL THEORY. Session 1 – The concept of feedback. Which block scheme represents the level control depicted in the picture below?. LC. Define servo and control problem. F out. Which block schemes represents the level control depicted in the picture?. h desired. F in. h. +. Controller.

Control Theory. Lachlan Blackhall and Tyler Summers. Control Theory. Advanced control methods are model based Use a mathematical model of the system to design controllers. u. System Dynamics. y. Controller. State Space Models. Inputs, outputs describe external behavior of system

Control Theory. D action – Tuning. Derivative Action. When there’s too much oscillation , this can sometimes be solved by adding a derivative action. This action will take into account how fast the error signal is changing . In the time domain this leads to :

Control Theory. Session 5 – Transfer Functions. Transfer function of . A B C None of the above. A. B. [Default] [MC Any] [MC All]. C. Step response of. z(t). A. t. B. Definition of step response: Δ z(t) if Δ u(t) is a step of size 1. A, B on previous graph?. A=2, B=3

Control Theory. Session 4 – Static Characteristics. The static process characteristic. Tells us A Tells us B. A- What the possible process equilibria are and is as such not dependent on properties of the control loop the process might be part of.

Control Theory. Bode Stability Criterion. Other view on stability of CL. Where the PHASE of the open loop TF equals -180°(+/-n.360°), we have positive feedback. If the AMPLITUDE RATIO at these frequencies > 0db: unstable closed loop. Two important measures. GAIN MARGIN

Control Theory. I and D. The formulas. About the pre-class quiz. I could solve it I couldn’t get started I could start, but I’m stuck somewhere I didn’t try. [Default] [MC Any] [MC All]. Integral Action. When an integrator is present in the loop: steady state error = 0.
