wecopttool.pto.PTO.acceleration

PTO.acceleration(wec, x_wec, x_opt, waves=None, nsubsteps=1)

Calculate the PTO acceleration time-series.

Parameters:

• wec (WEC) – wecopttool.WEC object.

• x_wec (ndarray) – WEC dynamic state.

• x_opt (ndarray) – Optimization (control) state.

• waves (Dataset | None) – xarray.Dataset with the structure and elements shown by wecopttool.waves.

• nsubsteps (int | None) – Number of steps between the default (implied) time steps. A value of 1 corresponds to the default step length.

Return type:

ndarray
