EECS 216 Fall 2010 Lab 4: Control The lab has been designed so that you can complete both in-lab and post-lab portions during the three-hour lab. Please plan on handing in your completed post-lab before you leave. 1 Laboratory Work (In-lab) All the circuits constructed as part of this laboratory use the 741 operational amplifier. 1.1 The following three figures illustrate the circuits and their protoboard layout for the present lab. Figure 1.1.1 shows the op-amp circuit realization of the PD controller, where the plant, P ( s ) appears as a separate component in the circuit. Further details about P ( s ) are given in Figure 1.1.2, which provides the appropriate op-amp circuit. Finally, Figure 1.1.3 provides a schematic for the overall layout of the protoboard. b x ( t ) ± ± ± A A A R 1 " " " b b b - + Op-amp 1 ± ± ± A A A R 1 p ( t ) ± ± ± A A A R 2 A ± ± ± A A A R 2 C b b b " " " - + Op-amp 2 " " " b b b - + Op-amp 3 ± ± ± A A A R 3 w ( t ) P ( s ) b y ( t ) Figure 1.1.1: Op-Amp Realization of PD Controller With 2-Degrees of Freedom 1

Use the signal generator to apply a unit step input, i.e., v i ( t ) = u ( t ), to the plant and observe on the oscilloscope both the input step (scope channel 1) and output step response, v o ( t ), (scope channel 2). Store these scope traces (plot and both channels of data) on the computer for later use. Note: The output step response should be of the form v o ( t ) = A + Be - αt cos( ω 0 t + φ ). (c) Using the oscilloscope, measure the oscillation frequency,
