blockCombiTable1Factor
CombiTable 1Ds, with input and output factors
Information
Blocks CombiTable1Factor and CombiTable2Factor implement the way EHTPlib uses matrices to determine components' behaviour such as torque limitation, optimal speeds, ICE consumptions, etc.
CombiTable1Factor is based on a MSL CombiTable1Ds, CombiTable2Factor on CombiTable2Ds.
These matrices can be directly written on the input mask, or taken from a file.
When they are taken from a file, it is very convenent to use factors on matrix inputs and output. This allows for instance to compensate usage of rpm instead of rad/s for speeds, or to re-use matrices in machines different from those they were originally written for, scaling input axes and ouptut.
For instance one could have a fuel consumption map of an ICE; which is adequate for a full family of engines: using these factors, it can be scaled to different speed/torque ranges, and omothetically varied also vertically (e.g. consumptions can be reduced to 90% by multiplication with an output factor equal to 0.9).
When matrix is not from a file, factors are automatically set to 1, and the input matrix is used without changes. When, instead, it is taken from a file, the two inputs are mutiplied by u1Factor and u2Factor respectively, and output by yFactor.
