Thus, in the system when performing the mentioned conditions the processes will have the character of the decaying exponential with time constant:

Consequently, the installation of the disk head at a given track in the control system will occur within 2-3 msec.
To construct the scheme represent the compensator transfer function of the compensator (fig. 2.1) as:

	(2.9)

Hence, we obtain:

	(2.10)

,where		– proportional component of the control head
disk

	– an integral component of the current management
	–Differential component of the control amperage

In order to ensure physical implementation of differential

component of the control amperage		we use real
