Member Function Documentation

planOnce()

Eigen::Vector2d CCC::IntrinsicallyStableMpc::planOnce	(	const std::function< RefData(double)> &	ref_data_func,
		const InitialParam &	initial_param,
		double	current_time,
		double	control_dt = -1
	)

Plan one step.

Parameters

ref_data_func	function of reference data
initial_param	initial parameter
current_time	current time (i.e., start time of horizon) [sec]
control_dt	control timestep used to calculate ZMP (if omitted, horizon_dt is used)

Returns

planned ZMP
