MATLAB: Where can I find a list of recognized unit symbols for the PS-Simulink Converter and the Simulink-PS Converter blocks in SimHydraulics 1.0 (R2006a+)

Question

The documentation does not list a valid set of parameters for the PS-Simulink Converter and the Simulink-PS Converter blocks in SimHydraulics 1.0 (R2006a+).

Answer 1

A list of valid units has been included in the documentation of SimHydraulics 1.1 (R2006b) under the title 'Unit Definitions'. This list was moved to the Simscape documentation in Simscape 1.0 (R2007a).

Use the following rules to specify unit symbols for the PS-Simulink Converter and the Simulink-PS Converter blocks in SimHydraulics 1.0 (R2006a+).

All the units are divided into two groups:

1. Those that are assigned a unique name, and

2. Those that are derived from these units.

The first group is:

Length: m, mm, cm, km, in, ft, mi, yd

Volume: l, gal

Mass: g, mg, lbm, oz, slug

Force: N, lbf, dyn, lb

Time: s, min, hr

Angle: rad, deg, rev

Linear velocity: mph, fpm, fps

Angular velocity: rpm

Energy: J, Btu

Power: W, HP

Electrical units: V, A, F, H, Ohm

Pressure: Pa, bar, psi, atm

Flow rate (volumetric): lpm, gpm

Viscosity absolute: Poise, cP, reyn

Viscosity kinematic: St, cSt, Newt.

The derived units of the second group are created by applying multiplication, division, and power operations.

Any unit from the first or second group can be used in the Simulink-PS and, accordingly, in the PS-Simulink converters.
