Conference paper (peer-reviewed)abstract
- Modular implementation of discrete event models in Programmable Logic Controllers (PLCs) using Sequential Function Charts (SFCs) is investigated. Synchronisation of such models, typically finite state automata of Petri nets, is not well defined in the synchronous PLC-world. We develop an algorithm that computes event monitors for synchronising concurrently executing SFCs. The methodology is applied to an assembly cell.

The Mechatronics Control Kit for Education and Research
- 2001

In: Proceedings of the 2001 IEEE International Conference on Control Applications, 2001. (CCA '01).. - 0780367332 ; , s. 105-110

Conference paper (other academic/artistic)abstract
- We discuss the use of the Mechatronics Control Kit from Mechatronic Systems, Inc. for control education and research. The Mechatronics Control Kit can be configured with several distinct plants, including a simple DC motor, an inertia wheel pendulum and a Pendubot. The digital electronics are fully integrated and include a Texas Instruments DSP development system, the TMS320C6711 DSK Board (a DSP board with parallel port interface), a PWM output/optical encoder input data acquisition daughter board, a PWM amplifier, and power supplies. We discuss the hardware and software interface and outline a set of experiments that can be performed using this system

Safe Manual Control of the Furuta Pendulum
- 2001
-
In: Proceedings of the 2001 IEEE International Conference on Control Applications, 2001. (CCA '01).. - 0780367332 ; , s. 890-895
-
Conference paper (peer-reviewed)abstract
- This paper deals with the manual control of unstable systems, subject to control signal saturation. In particular we consider the Furuta pendulum, where the problem is to control the orientation of the arm manually while stabilizing the inverted pendulum. This paper presents an analysis which leads to an insight into the problem as well as the control strategy. This control strategy has been implemented on the real Furuta pendulum. Aspects of the implementation as well as experimental results are discussed
