Tank steering systems allow a tank, or other continuous track vehicle, to turn. Because the tracks cannot be angled relative to the hull (in any operational design), steering must be accomplished by speeding one track up, slowing the other down (or reversing it), or a combination of both.
Speed wobble (also known as shimmy, tank-slapper, [1] or death wobble) is a rapid side-to-side shaking of a vehicle's wheel(s) that occurs at high speeds and can lead to loss of control. It presents as a quick (4–10 Hz) oscillation of primarily the steerable wheel(s), and is caused by a combination of factors, including initial disturbances ...
The most effective methods generally involve developing some form of process model and then choosing P, I, and D based on the dynamic model parameters. Manual tuning methods can be relatively time-consuming, particularly for systems with long loop times. The choice of method depends largely on whether the loop can be taken offline for tuning ...
The Ziegler–Nichols tuning method is a heuristic method of tuning a PID controller. It was developed by John G. Ziegler and Nathaniel B. Nichols . It is performed by setting the I (integral) and D (derivative) gains to zero.
Military theory is the study of the theories which define, inform, guide and explain war and warfare. Military Theory analyses both normative behavioral phenomena and explanatory causal aspects to better understand war and how it is fought. [ 1 ]
The most common application of tank circuits is tuning radio transmitters and receivers. For example, when tuning a radio to a particular station, the LC circuits are set at resonance for that particular carrier frequency. A series resonant circuit provides voltage magnification. A parallel resonant circuit provides current magnification.
The ship model basins worldwide are organized in the ITTC [3] (International Towing Tank Conference) to standardize their model test procedures. Some of the most significant ship model basins are: Denny Tank in Dumbarton, Scotland. The Denny tank was the first commercial ship model basin.

H ∞ (i.e. "H-infinity") methods are used in control theory to synthesize controllers to achieve stabilization with guaranteed performance. To use H ∞ methods, a control designer expresses the control problem as a mathematical optimization problem and then finds the controller that solves this optimization.
