% A RWA model using FrictionSmooth.
You will initialize to a Honeywell HR0610 model. Only marketing sheet data is
used.
This model uses FrictionSmooth to model the friction.
k = RWA( 'initialize' ); Initializes the wheel
k = RWA( 'initialize', [], k ); Initializes the wheel(s)
x = RWA( 'get tachometer measurement', [], k ); Gets the wheel speed
d = RWA( 'get default datastructure', [], k ); Gets the default RWA data
d = RWA( 'get datastructure', [], k ); Gets the RWA data
x = RWA( 'get power', [], k ); Gets the power.
x = RWA( 'get current', [], k ); Gets the power from d
x = RWA( 'get motor voltage', [], k ); Gets the motor voltage.
RWA( 'put voltage', vIn, k ); Puts the voltage into d
x = RWA( 'compute torque', [], k ); Computes torque
RWA( 'torque speed curve', omega, k ); Plots the torque speed curve
if omega is [] it will use a
default rate vector. Omega
must be a 1-by-n array.
k can be a number or a tag.
A typical calling sequence is
RWA;
loop:
d = RWA( 'put voltage', voltageIn, k );
[torque, d] = RWA( 'compute torque', omega, k );
power = RWA( 'get power', [], k );
current = RWA( 'get current', [], k );
voltage = RWA( 'get motor voltage', [], k );
end loop;
Since version 3.
