“…This situation is solved in [11] by applying a predictor/corrector numerical integration method (a combination of forward and backward Euler solver). The aforementioned emulators [9][10][11] are, in essence, custom, low-cost solutions. Professional tools are also available, such as eFPGASIM [12], a powerful and intuitive FPGA-based emulator.…”

“…Our solution is compared with existing ones, given in refs. [9][10][11][12]; • A digital proportional-integrative-derivative (PID) controller design method was devised using emulated hardware (real-time simulation). The hardware emulation allows the designer to manually tune the PID controller coefficients, without any harm to the actual power stage.…”

This paper proposes a methodology of delivering the emulation hardware of several step-down converter power stages. The generalized emulator design methodology follows these steps: first, the power stage is described using an ordinary differential equation system; second, the ordinary differential equation system is solved using Euler’s method, and thus an accurate time-domain model is obtained; next, this time-domain model can be described using either general-purpose programming language (MATLAB, C, etc.) or hardware description language (VHDL, Verilog, etc.). As a result, the emulator has been created; validation of the emulator may be carried out by comparing it to SPICE transient simulations. Finally, the validated emulator can be implemented on the preferred target technology, either in a general-purpose processor or a field programmable gate array. As the emulator relies on the ordinary differential equation system of the power stage, it has better behavioral accuracy than the emulators based on average state space models. Moreover, this paper also presents the design methodology of a manually tuned proportional–integrative–derivative controller deployed on a field programmable gate array.

“…The validation of control systems must be done in a series of steps, obeying design requirements. One of the strategies for system development that allows such procedures is Model-Based Design (MBD), which is being widely used today [25]. This methodology offers a systematic way to handle the development of complex control systems through a visual and mathematical approach and has been recognized for assisting systems development, becoming standard practice in systems engineering [26].…”

The increasing need for testing and prototyping designs under more realistic conditions is responsible for the advancement of new types of simulation. In this scenario, one type of simulation which has gained high notoriety and applicability is the one known as Hardware-in-the-Loop (HIL). This technique allows real and virtual components of a system to be tested together, making it possible to perform tests under realistic (and even extreme) conditions without harming the real system or a prototype built only for testing. The objective of this work was to develop a low-cost HIL simulation platform to be used for many different applications, unlike most commercial ones, that are developed for one exclusive field of application, such as automotive, aerospace, power electronics, among others. Thus, the main contribution of this work is the project of a HIL platform capable of simulating different types of systems, making it possible to validate embedded control strategies designed for them. Two different applications are tested in order to validate the HIL platform: an active suspension and a satellite attitude control air bearing table, both controlled using a discrete Linear Quadratic Regulator (LQR) designed for each of them.INDEX TERMS Active suspension systems, control systems, hardware-in-the-loop, satellite attitude control.
