TakeOffTrajectoryController

class sharpy.controllers.takeofftrajectorycontroller.TakeOffTrajectoryController[source]

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

Name Type Description Default
trajectory_input_file str Route and file name of the trajectory file given as a csv with columns: time, x, y, z None
dt float Time step of the simulation None
trajectory_method str Trajectory controller method. For now, “lagrange” is the supported option lagrange
controlled_constraint str Name of the controlled constraint in the multibody context Usually, it is something like constraint_00. None
controller_log_route str Directory where the log will be stored ./output/
write_controller_log bool Controls if the log from the controller is written or not. True
free_trajectory_structural_solver str If different than and empty string, the structural solver will be changed after the end of the trajectory has been reached  
free_trajectory_structural_substeps int Controls the structural solver structural substeps once the end of the trajectory has been reached 0
initial_ramp_length_structural_substeps int Controls the number of timesteps that are used to increase the structural substeps from 0 10
control(data, controlled_state)[source]

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_statedict 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.
