The integ operator lets you perform time integration of an expression in the equations section of a Simscape file without declaring and initializing extra variables.
The full syntax is:
integ(expr,t_L)
where:
• expr is a Simscape language expression.
• t_L is the lower integration limit, specified as a delay time relative to the current time. This operand is optional.
The upper integration limit is the current simulation time. If you omit the lower limit, the integration starts from the simulation start time. expr can be of any type. It will automatically be converted to a double.
integration variable.
• expr is assumed to have zero history for times prior to start of simulation.
• t_L must be a scalar nonnegative constant or parametric expression with the unit of time.
The return unit of integ is the unit of its operand multiplied by a unit of time.
It looks like tinit = {0,'S'} and t = {0,'S'}, the correct unit of time is small 's' not capital 'S'.
