PID controller block
-
class
idaes.dynamic.pid_controller.PIDBlock(*args, **kwargs) This is a PID controller block. The PID Controller block must be added after the DAE transformation.
- Args:
rule (function): A rule function or None. Default rule calls build(). concrete (bool): If True, make this a toplevel model. Default - False. ctype (str): Pyomo ctype of the block. Default - “Block” default (dict): Default ProcessBlockData config
- Keys
- pv
- A Pyomo Var, Expression, or Reference for the measured process variable. Should be indexed by time.
- output
- A Pyomo Var, Expression, or Reference for the controlled process variable. Should be indexed by time.
- upper
- The upper limit for the controller output, default=1
- lower
- The lower limit for the controller output, default=0
- calculate_initial_integral
- Calculate the initial integral term value if true, otherwise provide a variable err_i0, which can be fixed, default=True
- initialize (dict): ProcessBlockData config for individual elements. Keys
- are BlockData indexes and values are dictionaries described under the “default” argument above.
- idx_map (function): Function to take the index of a BlockData element and
- return the index in the initialize dict from which to read arguments. This can be provided to overide the default behavior of matching the BlockData index exactly to the index in initialize.
- Returns:
- (PIDBlock) New instance
