Library Simulink - Quarc

The library also includes that interface with specific drivers (e.g., HIL Initialize , HIL Read Analog , HIL Write PWM ).

: In teaching laboratories, QUARC is an integral part of Quanser's workstations. It allows students to focus on core control concepts like PID, LQR, and state-feedback design rather than on low-level code writing. For example, a typical first-year lab exercise involves using QUARC blocks to output a voltage to a DC motor, read the resulting angular position from an encoder, and display it in a Simulink scope. The System Timebase block serves as a useful teaching tool for demonstrating real-time simulation concepts without the overhead of code generation, though its limitations are clearly documented.

QUARC transforms Simulink from a pure simulation environment into a powerful, real-time control software suite. By generating hard real-time code directly from Simulink models, it eliminates the need for manual C/C++ coding, drastically reducing development cycles.

– Perhaps one of the most valuable features for control system development is the ability to tune block parameters while the real-time code is running. Simply double-click on a block, change a parameter, and the update is automatically downloaded to the running application.

The QUARC library will appear in the Simulink Library Browser. The library also includes that interface with specific

: These blocks are used for complex signal management tasks, such as routing an input signal to one of several outputs or replacing elements of a signal.

QUARC is widely considered the "gold standard" for real-time control prototyping within the MATLAB/Simulink environment, particularly in academic and high-end research settings. For example, a typical first-year lab exercise involves

: This category supports multimedia devices, including blocks for video capture and integration with the Microsoft Kinect sensor. It also includes blocks for force-feedback game controllers and speech synthesis.

: This is arguably the most essential category for hardware interaction. It contains blocks that provide direct access to various data acquisition cards, allowing your Simulink model to read from sensors and write commands to actuators.

: These blocks offer advanced continuous-time functionality beyond Simulink’s native set. Key blocks include the Nonlinear State-Space block for implementing custom ODEs like x_dot = f(x,u) , an Extended Kalman Filter for state estimation in nonlinear systems, and a Controller block that can implement three commonly used controllers simultaneously.
