SIMPLIFICATION OF LINEAR DYNAMIC SYSTEMS

Simplification of a Petri Net controller in industrial systems

This paper deals with the problem of forbidden states in discrete event systems modeled by Petri Net. To avoid the forbidden states, some constraints which are called Generalized Mutual Exclusion Constraints can be assigned to them. Enforcing these constraints on the system can be performed using control places. However, when the number of these constraints is large, a large number of control p...

Simplification of Turning Point Problems for Systems of Linear Differential

dynamic coloring of graph

در این پایان نامه رنگ آمیزی دینامیکی یک گراف را بیان و مطالعه می کنیم. یک –kرنگ آمیزی سره ی رأسی گراف g را رنگ آمیزی دینامیکی می نامند اگر در همسایه های هر رأس v?v(g) با درجه ی حداقل 2، حداقل 2 رنگ متفاوت ظاهر شوند. کوچکترین عدد صحیح k، به طوری که g دارای –kرنگ آمیزی دینامیکی باشد را عدد رنگی دینامیکی g می نامند و آنرا با نماد ?_2 (g) نمایش می دهند. مونت گمری حدس زده است که تمام گراف های منتظم ...

A Simplepole Clustering Technique for Dynamic Systems Simplification

A simple clustering technique is presented in this paper to simplify the dynamic system via reducing the order of its transfer function. The reduced denominator polynomial of thesimplified model is determined by a simple pole clustering technique and the numerator coefficients are obtained byusing improved Pade approximations method. The dominant pole of a cluster may be inside or outside of th...
