This article should be about dead time in general, about any process. --Thydzik 06:28, 14 August 2006 (UTC)
Paralize
[edit]This article uses "paralizable", but wiktionary prefers paralysable, and the major reference for this article (Leo) uses "paralyzable", which is also the clear winner according to Google. I have left the spelling as is for now, since the major dictionaries I quickly looked at do not have the word, and I am not familiar with wiktionary etiquette for handling poorly established spellings.

- I have replaced all instances with "paralyzable" for now (I suspect the difference between "paralyse" and "paralyze" comes down to English/American English). It seems to have the most support in peer-reviewed articles and I can only find this on one or two personal websites. In any case it seems like the most logical origin for the word in this context. -- Newty 16:19, 9 April 2012 (UTC)
Other uses
[edit]This is commonly used in motor control. When a phase changes, the electro-magnets will reverse polarity. You can not connect the drive transistors together and need to let the motor briefly coast through this portion. The time that the motors are undriven (commutation) is often called dead time. In control systems, there is often a delay between actuation of an element and when the physicals action happens. This is not modelled by classical PDE analysis. However, structures like a PID can handle this type of dead time without modification, but parameter tuning must take into account this 'dead time'. Example search FODT control, which is common for thermal systems. Finally, the 'dead time' can be in a signal. For instance, it is common in audio to refer to silence as 'dead time'. So an inactive signal can be referred to as 'dead time'. There are obvious parallels to the motor commutations. This seems to be the thrust of what Thydzik is saying; the article is referring to 'system dead time' (and mainly composed for special applications that are only of note to a physicist, when it is much more generic) 66.244.255.122 (talk) 18:06, 8 November 2023 (UTC)
