This paper presents the development and implementation of a Rapid Control Prototyping (RCP) System. Key features of RCP are working with simulink block sets, automation of code generation and automatic downloading of executable code to the target DSP. In such manner, control algorithms can be rapidly integrated or adapted in no time. Simulink integrated with DSP TMS320F28335 provides a useful development tool for design verification of control algorithms, suitable for different plants. Through the use of RTW (Real Time Workshop) functionality, different modules on custom made DSP board are developed, which are needed to create an environment that is suitable for processing execution. Software has been developed with the use of Simulink block sets. Some of them have been provided from TIC2000 library. More complex blocks have been developed with the use of S-functions and TLC, target language compiler. Design and realization of regulation algorithms for stabilization of rotary inverted pendulum are presented.

This study presents the implementation of a hybrid control strategy that is applied to a brushless AC (BLAC) motor drive. Hybrid control is a general approach for control of switching-based hybrid systems (HS). This class of HS includes a continuous process, controlled by a discrete controller with a finite number of states. The overall stability of the system is shown with the use of Lyapunov technique. The Lyapunov functions contain a term that penalises incremental energy of control error, torque and stator current, which enhances the stability. The closed-loop system, with the proposed control law, provides good transient response and good regulation of the BLAC motor control. A new logical field programmable gate array current (torque) controller is developed, based on the Lyapunov theory. The reference tracking performance of speed and torque (current) is demonstrated in terms of transient characteristics through simulation and experimental results. © 2011 The Institution of Engineering and Technology.
