Annotated PID Controller in SWMM5 and InfoSWMM

Image
How does a PID controller work in  InfoSWMM  and SWMMM 5 - this also applies to H2OMap SWMM?? double getPIDSetting(struct TAction* a, double dt)   //  at each time  step find  the PID control  changes for the  current  time step dt
// Input: a = an action object
// dt = current time step (days)
// Output: returns a new link setting
// Purpose: computes a new setting for a link subject to a PID controller.

// Note: a->kp = gain coefficient,
// a->ki = integral time (minutes)
// a->k2 = derivative time (minutes)
// a->e1 = error from previous time step
// a->e2 = error from two time steps ago
{
double e0, setting;
double p, i, d, update;
double tolerance = 0.0001; // --- convert time step from days to minutes
dt *= 1440.0; // --- determine relative error in achieving controller set point // Or how close are we to the set point?
e0 = SetPoint - ControlValue;
if ( fabs(e0) > TINY )

if ( SetPoint != 0.0 ) e0 = e0/SetPoint; // now alter the  value of e0
else e0 = e0/Contr…

Oregon’s Clean Water Services Adopts SWMMLive and InfoMaster Technology

Oregon’s Clean Water Services Adopts SWMMLive and InfoMaster Technology Real-Time Sewer Network Modeling and Analytics-Driven Risk-Based Asset Management Software to Improve Business Planning, Infrastructure Sustainability and Resiliency Broomfield, Colorado, USA, May 3, 2016 — Innovyze, a leading global innovator of business analytics software and technologies for smart water infrastructure, today announced that Clean Water Services (District), Oregon, has chosen the company’s industry-leading and award-winning InfoMaster and SWMMLive to support its sanitary sewer capital improvement program. The purchase will enable the District to efficiently upgrade, replace and expand its infrastructure and improve water quality in the Tualatin River and its tributaries. Headquartered in Hillsboro, Oregon, Clean Water Services is a water resources management utility that combines science and nature to clean water and return it to the Tualatin River so it can be used again. The District cleans more …

Why is a Hot Start File important in SWMM 5 and InfoSWMM

Image
A Hot Start File in InfoSWMM  or SWMM 5 is important as it provides initial   depths, initial flows and  initial settings for the hydrology and hydraulics features of the SWMM 5 engine.    You  have three options: Save a hot Start File at the  end of the  simulation,Use a hot Start File  at the beginning of  the simulation,Create a hot start file  from  the a  time during  the  Map Display If you change any of the network  types or add new links and nodes then  the Hot Start file needes to be recreated.  InfoSWMM use the Tab File in  the Run Manager to name the Hot Start File (Figure 1).   Each and  every Scenario in InfoSWMM  can  use or Save a different scenario with different starting  and ending  times  (Figure 2).  If you USE  a Hot  Start  File then: The  new  simulation  starts at the end  of  the  old  simulationYou can  run a Quasi Steady State Simulation and use a very short simulation time of minutes if you use a Hot Start FileFigure 3  shows  the effect of Using a Hot Start…
