This is closely tied to the minimum weight to length ratio of cycles in the diagram, which is not obviously directly dependent on m. This observation should also be true about T,,,~” in Hemmati and Costello [3], though 7min is of the order of four to six times m for the examples they consider. The fact that low weight cycles in the state diagram cause the requirement that the guard space be lar...

In this paper, a fuzzy logic controller approach is presented for twin rotor multi-input-multi-output (MIMO) system in order to improve the control of pitch and yaw motions under hovering conditions. Twin rotor MIMO system resembles a helicopter model in some common aspects like cross coupling of pitch and yaw motions. The proposed approach is compared with another control strategy by simulatio...

Interest in system identification especially for nonlinear systems has significantly increased in the past few decades. Soft-computing methods which concern computation in an imprecise environment have gained significant attention amid widening studies of explicit mathematical modelling. In this research, an adaptive neuro-fuzzy inference system (ANFIS) network design is deployed and used for m...

Identifying and removing the causes of poor performance in software systems are complex problems, and these issues are usually tackled after software deployment only with human-based means. Performance antipatterns can be used to harness these problems since they capture design patterns that are known leading to performance problems, and they suggest refactoring actions that can solve the probl...

This paper deals with model predictive control (MPC) approach for a 2 DOF (degree of freedom) helicopter. The main objective is to stabilize beam of the 2DOF helicopter with respect to pitch and yaw angles. Development of controller for 2DOF helicopter is challenging because of its coupling effects between two axes and also due to its highly nonlinear characteristics. An accurate model of the s...
