| What's the matter with my home-made gyrostat and anemometer? |
| It is assumed that the parameters of the gyrostat system are completely unknown in advance and the system is perturbed by unknown uncertainties and disturbances. |
| At present the balance-weight is so placed that the gyrostat would fall if it were not spinning. |
| There is, however, a great difference between the earth and the gyrostat. |
| But now remove the gyrostat from the frame, and set the wheel in rotation. |
| Figure 15 shows one form of gyrostat mounted on a horizontal frame, held in the hands of an experimenter. |
