Question

Report task. A standard closed-loop control system is shown in Figure 6. Classify the different components and signals of the electronic compass system in the control engineering terms used in Figure 6, i.e. which components represent the controller, which the plant, what is the output signal, what the actuation signal. Reference Control Actuation Output error Controller signal Pant signal Y (s) value R(s) + U(s) E(s) K (s) G(s) Measured output signal Y (s) H(s) Measurement Figure 6: Basic control loop in Laplace-domain

Answer 1

the reference signal is the desired output.
The difference between the reference signal and the output is called the error signal.
This signal goes through the controller K(s) and turns into the actuation signal to correct the error.
The actuation signal actuates the plant to obtain the response y(t) which then sensed by the measurement unit whose Laplace transform is given by H(s). The output from the measurement unit is fed back to the summer which then computes the error signal e(t) whose Laplace domain equivalent is E(s). This is how the closed-loop control system works.
