ATOMIC PDEVS step_qss1

stored in DEVS_PATH/01-modelbase/qss/step_qss1.m

Description

Class definition file for an atomic PDEVS model for generating a step (source) for use with qss1 models.

constructor call: obj = step_qss1(name,inistates,elapsed,T,v)

atomic (superclass acts as associated simulator)

characteristic functions:

ta = tafun(obj) : time advance function - calculates time until next internal event by evaluating the states in s
deltaconffun(obj,gt) : confluent function - calculates from states s, inputs x and elapsed time elapsed the new states s', if there is an internal and an external event at the same time
deltaextfun(obj,gt) : external transition function - calculates from states s, inputs x and elapsed time elapsed the new states s'
deltaintfun(obj) : internal transition function - calculates from states s the new states s'
lambdafun(obj) : output function calculates from states s the ouptputs y

display functions:

inherited from atomic:

name : string, (unique) name of this model --> for debugging purposes max. 12 characters for "nice" debug-look ;-)
x : structure, set of inport name/input value pairs
y : structure, set of outport name/output value pairs
s : structure, set of states
sysparams : structure, set of system parameters, can be set only once at instantiation
elapsed : float, time elapsed since last transition (only for initialization)

debug_flag: 0|1|2|3, no messages|messages|steps|visualize x, y, and s (default 0)
observe_flag: 0|1, log states of atomic subcomponents or not (default 0)
observed : cell array including time stamps and a copy of s (structure of states)

has no input x (is source)

has one output y : p1

s.sigma : for time advance

s.j : to store active indices in vectors sysparams.T and sysparams.v

sysparams.T : [0, steptime, stepduration], times for step

sysparams.v : [v_before, v_after], values for step

global SIMUSTOP : can be used to stop allover simulation e.g. when a predefined number of jobs has finished
