Double Integrator

In the double integrator problem, we seek to maximize the distance traveled by a block (that starts and ends at rest) sliding without friction along a horizontal surface, with acceleration as the control.

We minimize the final time, t_f, by varying the dynamic control, u, subject to the dynamics:

\begin{align} \frac{dx}{dt} &= v \\ \frac{dv}{dt} &= u \end{align}

The initial conditions are

\begin{align} x_0 &= 0 \\ v_0 &= 0 \end{align}

and the final conditions are

\begin{align} x_f &= \rm{free} \\ v_f &= 0 \end{align}

The control u is constrained to fall between -1 and 1. Due to the fact that the control appears linearly in the equations of motion, we should expect bang-bang behavior in the control (alternation between its extreme values).

The ODE System: double_integrator_ode.py

This problem is unique in that we do not actually have to calculate anything in the Dymos formulation of the ODE. We create an ExplicitComponent and provide it with the num_nodes option, but it has no inputs and no outputs. The rates for the states are entirely provided by the other states and controls.

class DoubleIntegratorODE(om.ExplicitComponent):
    """
    The double integrator is a special case where the state rates are all set to other states
    or parameters.  Since we aren't computing any other outputs, the ODE doesn't actually
    need to compute anything.  OpenMDAO will warn us that the component has no outputs, but
    Dymos will solve the problem just fine.

    Note we still have to declare the num_nodes option in initialize so that Dymos can instantiate
    the ODE.

    Also note that neither time, states, nor parameters have targets, since there are no inputs
    in the ODE system.

Building and running the problem

In order to facilitate the bang-bang behavior in the control, we disable continuity and rate continuity in the control value.
