Consider the block diagram of a feedback control system in Fig. 11.8, where K_m= 1, G_p= 1 / s + 1, G_d= 0, G_v= K_ve^ˆ’s, G_c= 1, and G_m= 1. A control engineer claims that the process will exhibit an inverse response to changes in set point, due to the presence of a time delay in the dynamics of the actuator G_v. Prove or disprove this assertion.
