PDServo is a linear math model of a proportional/psuedo derivative control system. This means that the feed forward compensation is proportional and the feedback compensation is both proportional and differential. This is most common in electric motor servos with tachometer as well as potentiometer feedback
Chained reactions (CplxCalPro) - The present document has been written as an introduction to the emulation of successive chained biochemical reactions with the CplxCalPro graphical calculator on a Palm platform.
The law which, in this instance, was assumed to link the variables is similar to other ones found in various fields of human knowledge
PDAcalc units (PocketPC) is a conversion calculator that can quickly and easy translate different units of measure. It can translate days into seconds, Celsius into Fahrenheit, foreign currency into domestic currency, how many gallons a container of certain dimensions can hold, and much much more
PDAcalc matrix (PocketPC) - Use this calculator for your basic and linear algebra calculations. Using matrices allows you to perform far more powerful calculations with less instructions. Instead of using one value at the time use a matrix or vector containing hundreds of values. Features:
Uses same syntax as high-end mathematical programs like matlab
