This paper discusses the automatic generation of controller codes through a model created in the MATLAB environment the aim of the research is to simplify the implementation and tuning of the closedloop circuit in industrial systems in this context, the concepts and steps outlined herein could produce a more intuitive and powerful alternative to the pre-defined software components of control systems that enable closed-loop control. We propose a methodology for identifying the system through an industrial control setup, creating a control loop model, and generating a code implementable in the control setup. Importantly, we also present and compare the results obtained with various variants of the automatically generated control circuit containing a pre-defined controller of the industrial control system. The outcomes of the research allow us to conclude that the implementations generated by the model perform better that the option using a built-in controller.

“…That is, the ARM chip sends the command rotation velocity to the stepper motor control chip, which is responsible to convert the command velocity into corresponding pulse, according to pre-defined velocity profile. The algorithms run in the attitude sensor board and stepper motor control and drive board are firstly designed in Matlab/Simulink, and then converted into C code by the code generation tools [24][25][26].…”

Marine Satellite Tracking Antenna (MSTA) is an important shipboard device for ships to bidirectionally communicate with the outside. The attitude stabilization system is an important part of MSTA for keeping the antenna dish tracking the geostationary satellite in the presence of severe ship dynamics. In this paper, the designed high-performance attitude stabilization system is introduced, including hardware system, model identification and controller design. The detailed procedure for identifying the stepper motor model is stated, which is different from conventional procedure. The design procedure of the robust controller based on H ∞ loop shaping is given. The designed attitude stabilization system was tested on a Stewart platform that was used as the ship simulator. From the testing results, it can be seen that the performance of designed attitude stabilization system is very high and the tracking angle error can be limited to within ± 0.15 deg, which satisfies the performance requirements of Ka-band MSTA product.

“…In 1998 Toyota presented results at the Global Automotive Engineering Seminar showing that code generated by the Real-Time Workshop is only 5% larger and 15% slower than handwritten code. And there are reports of code generation being employed in safety-critical systems such as industrial PLCs [22], navigation and flight control systems [23] and experimental hypersonic scramjets [24].…”

This paper presents the development and preliminary results of a rapidly reconfigurable autopilot for small Unmanned Aerial Vehicles. The autopilot presented differs from current commercial and open source autopilots mainly as it has been designed to: (i) be easily reprogrammable via Simulink (models are directly transferred to the autopilot through the Real-Time Workshop's code-generation capability); (ii) decouple the traditional tasks of attitude estimation/navigation and flight control by using two Digital Signal Controllers (one for each task) interconnected via a Serial Peripheral Interface; and, (iii) being able to interact directly with Simulink as a Hardware-in-the-Loop simulator. This work details each of the main components of the autopilot and its ground control station software. Preliminary results for sensor calibration, Hardware-in-the-loop, ground and flight tests are presented.
