stable when a gain of 4 is unstable
The angle of wipers of a windshield can be modelled by the following transfer function: G(s) K(s+1) (s - 1)(s + 4) The root locus plot of the system, when K varies, is shown on Figure 02. 0.8 0.6 0.4 0.2 Auss 0 -0.2 -0.4 -0.6 -0.8 -6 -5 -3 -1 0 1 -2 Aaslais (encore) Figure 02:root locus plot a. State the type and the order of the system. Justify that the system is unstable. (2 marks) b. The system is controlled by a unity feedback. Draw the block diagram and state the transfer function for the controlled system. (4 marks) c. Verify that the system is unstable when K=4. Use the final value theorem and a step input. (2 marks)
