lynx.blocks.StateSpaceBlock

class lynx.blocks.StateSpaceBlock

Bases: Block

State space block with A, B, C, D matrices.

Parameters:

• A – State matrix (n x n)

• B – Input matrix (n x m)

• C – Output matrix (p x n)

• D – Feedthrough matrix (p x m)

For MVP (SISO systems): m=1 (single input), p=1 (single output)

Example

Second-order system: A = [[0, 1], [-2, -3]] B = [[0], [1]] C = [[1, 0]] D = [[0]]

Ports:

Input: in (single input for SISO) Output: out (single output for SISO)

Methods

__init__(id, A, B, C, D[, position, label])	Initialize state space block.
add_parameter(name, value[, expression])	Add a parameter to the block.
add_port(port_id, port_type[, label])	Add a port to the block.
get_parameter(name)	Get parameter value by name.
get_ports()	Get all ports as dictionaries.
is_input_marker()	Check if this is an input marker block.
is_output_marker()	Check if this is an output marker block.
set_parameter(param_name, value)	Update block parameter and sync to parent diagram.
to_dict()	Serialize block to dictionary for JSON export.

__init__(id: str, A: List[List[float]], B: List[List[float]], C: List[List[float]], D: List[List[float]], position: Dict[str, float] | None = None, label: str | None = None) → None

Initialize state space block.

Parameters:

• id – Unique block identifier

• A – State matrix

• B – Input matrix

• C – Output matrix

• D – Feedthrough matrix

• position – Optional {x, y} position on canvas

• label – Optional user-facing label (defaults to id)
