Possibly. Generally analog computers in "physical plants" would be used
to simulate the plant's operation. For instance, an oil refinery. The
computer would not control the plant, but various controls and valves
might be adjusted based on the model's response, when set-up to model
the production of some chemical or distillation product.
Most analog computers solve the same problem over and over again, to
produce an oscillograph or paper-graph - not for real-time operations.
Real-time may run faster or slower than the simulation. But, some labs
(psychology labs testing human or animal responses) might use an analog
computer to perform the test and record results.
