I have a custom System object that uses a configuration struct returned by a helper function:
classdef Demo_setpoint_adjuster < matlab.System
properties
config = Demo.getconfig;
end
methods
function obj = Demo_setpoint_adjuster()
% Optionally initialize config/state here if needed
end
end
methods(Access = protected)
function [adjusted_setpoint] = stepImpl(obj, setpoint)
% Default passthrough implementation
% Assign outputs
adjusted_setpoint = setpoint * obj.config.gain;
% TODO implement
end
function num = getNumInputsImpl(~), num = 1; end
function varargout = getNumOutputsImpl(~), varargout = {1, []}; end
function varargout = getOutputSizeImpl(~), varargout = {1}; end
function varargout = getOutputDataTypeImpl(~), varargout = {‘double’}; end
function varargout = isOutputComplexImpl(~), varargout = {false}; end
function varargout = isOutputFixedSizeImpl(~), varargout = {true}; end
end
end
My getconfig function looks like this:
function cfg = getconfig(varargin)
cfg = Simulink.Bus.createMATLABStruct(‘DEMO_config_def’);
cfg.gain = 10;
cfg.offset = 1e-13;
coder.cstructname(cfg, ‘my_struct’);
end % end of main function getconfig
When I generate code with Embedded coder, the header file defines the parameter type as something like:
typedef struct {
real_T gain;
real_T offset;
} struct_6h72eH5WFuEIyQr5YrdGuB;
Instead of my desired:
typedef struct {
real_T gain;
real_T offset;
} my_struct;
Even though I use coder.cstructname, Simulink still generates the anonymous struct_xxxxxx
Question:
When using a System object parameter inside a simulink model, how can i ensure embedded coder generates a struct with a specific typedef name (e.g., my_struct)? Is the recommended approach to use Simulink.Bus/Simulink.Parameter, or can coder.cstructname be applied directly in this workflow?I have a custom System object that uses a configuration struct returned by a helper function:
