Any circuit for driving a motor that's more complex than wiring it to a power source through a simple on/off switch. Examples include speed and torque control using H-bridges, brushless motor controllers, stepper controllers, VFDs. Constant speed examples include relay control, reversing, reduced-voltage starting, overload protection and other control requirements more complex than a simple 0n/off switch.

Is it possible to account for motor dead-band in a Laplace model of a feedback DC motor system?

For practical DC motors having dead-band effects, where the output angular speed of the DC motor remains zero until a large-enough DC voltage is applied to the motor system --- is it possible to appro …
