✦ Synopsis

Recent papers by M. G. Singh and M. F. Hassan describe a new multi-level (two or three) method to solve nonlinear optimisation problems and its application to the stabilisation of a synchronous machine. The author in this article makes several comments about a paper which appeared in Automatica recently (Hassan and Singh, 1976).

A new two level method is developed for the optimization of non-linear dynamical systems with a quadratic cost function. This method used an expansion around the equilibrium point of the system to fix the second and higher order terms. These terms are compensated for iteratively at the second level

The new idea of calculation of limit cycles of strongly non-linear systems and its several numerical examples were presented in [1]. It is interesting to study the calculation of limit cycles of non-linear systems further, however some defects have been found in [1].
