Initialize() [1/2]

void state_space::Initialize

(

const char *

filename

)

Initialize with a filename.

Initialize the model from an ASCII text engine data file.

The matrices are a b c d Each begins with [ and ends with ]

Parameters

filename

The file name

Initialize() [2/2]

void state_space::Initialize	(	const ml_matrix &	a,
		const ml_matrix &	b,
		const ml_matrix &	c,
		const ml_matrix &	d
	)

Initialize with matrices.

Initialize the state space system x(k+1) = ax(k) + bu(k) y(k) = cx(k) + du(k).

Parameters

a	State transition matrix
b	Input matrix
c	Output matrix
d	Feedthrough matrix

RHS()

ml_matrix state_space::RHS	(	const ml_matrix &	x,
		const ml_matrix &	u
	)

Update the right-hand-side.

Parameters

x	State
u	Input

Returns

Updated state

CheckDimensions()

bool state_space::CheckDimensions

(

void

)
