Abstract
A rotary tablet press comprises a rotor comprising a rotary drive configured to rotate the rotor and a die plate that rotates with the rotor and comprises a plurality of cavities and a plurality of upper and lower punches. A rotational speed governor is configured to drive the rotary drive of the rotor by comparing a measured rotor rotational speed with a target rotational speed value. A pilot control apparatus is configured to provide an additional target torque for driving the rotary drive. The additional target torque is based on values of a pressing force of at least one of the upper and lower punches input into the pilot control apparatus.
