ControlSurfacePidController

class sharpy.controllers.controlsurfacepidcontroller.ControlSurfacePidController

The settings that this solver accepts are given by a dictionary, with the following key-value pairs:

Name	Type	Description	Default
time_history_input_file	str	Route and file name of the time history of desired state	None
P	float	Proportional gain of the controller	None
I	float	Integral gain of the controller	0.0
D	float	Differential gain of the controller	0.0
input_type	str	Quantity used to define the reference state. Supported: pitch	None
dt	float	Time step of the simulation	None
controlled_surfaces	list(int)	Control surface indices to be actuated by this controller	None
controlled_surfaces_coeff	list(float)	Control surface deflection coefficients. For example, for antisymmetric deflections => [1, -1].	[1.0]
write_controller_log	bool	Write a time history of input, required input, and control	True
controller_log_route	str	Directory where the log will be stored	./output/

control(data, controlled_state)

Main routine of the controller. Input is data (the self.data in the solver), and currrent_state which is a dictionary with [‘structural’, ‘aero’] time steps for the current iteration.

Parameters

• data – problem data containing all the information.

• controlled_state – dict with two vars: structural and aero containing the timestep_info that will be returned with the control variables.

Returns

A dict with structural and aero time steps and control input included.
