If a heater is controlled by turning it on and off, does a PID algorithm help in more closely controlling the temperature? Will running the PID loop faster than the temperature measurement improve anything? How would a PID control be an improvement over a simple temperature comparison with or without an anticipator? -- Rick

I know many of your old farts here have a collection of schematics or at least manuals.... I can not find the manual or maybe even the schematic that sometimes comes with these manuals for a : Fincor 105456401 , 1900-77 This is a PID dancer controller with a tach following option. If need be I can reverse engineer one using TinyCad or some common free electronic ...

I understand the basics of PID design, but if you can't describe the thing being controlled, how can you design the controller other than trial and error? The "plant" is a motor on a tall reducing gear (~300:1) turning an arm that presses on a bag producing an air flow with the loop controlled by a pressure measurement. One issue I'm seeing discussed is a tradeoff on the

Imagine a mass that we want to heat with some closed-loop controller. It's C2 below. Voltage represents temperature. Thermal systems are diffusive, which we represent as a bunch of RC lags. Assume the voltage at C4 is the temperature sensor. If I were to design a PID controller, I'd have to really think about it, or fiddle some, to keep it stable. But if I do a dumb on/off thermostat, ...

I am having a difficult problem on a current project so I was wondering if anyone could help. This is a project where I have to measure current generated by a sample at high temperature inside a furnace. The current is in the picoamp-nanoamp range depending on temperature and I have been using a Keithley picoammeter. The furnace is controlled by a PID temp controller connected to

Garmin makes an "integrated" FM traffic info receiver for some models of GPS that allows connection to the car's AM/FM antenna. But not my model (Nuvi 660); I must use only the GTM20, a cigarette-lighter-powered model: Benefits of using the car's antenna are mostly stealth: the cord-that-is-the-antenna between the cigarette lighter (which w
