Slicot Drives Tractors! 1

We describe the successful application of a SLICOT subroutine in a control engineering problem. Based on GPS data it is possible to automatically steer farm vehicles along a prescribed trajectory. The bottleneck for the successful on-line implementation of a LQG regulator is the numerical solution of a discrete-time algebraic Riccati equation in real-time and at high accuracy. This is achieved ...

Power Hop Instability of Tractors

Power hop is a “porpoising” type of pitch/bounce oscillation superimposed on the forward motion of tractors equipped with pneumatic tires. It is most often observed with tractors having two powered axles pulling towed implements in moderate to high draft field operations on dry soils. As power hop begins, the tractor exhibits gradually increasing vibration amplitudes until the operator, of nece...

Elisha Perkins and His Metallic Tractors

Hocus! pocus! up and down! Draw the white right from the crown! Hocus! pocus! at a loss! Draw the brazen rod across! Hocus! pocus! down and up! Draw them both from foot to top! Wooden nutmegs and counterfeit money are not the only frauds that have had their origin in Connecticut. To the members of the medical profession Perkins' Metallic Tractors are of the most interest. immediately began the ...
