AbstructA unifying temporal logic framework is proposed for modelling, specifying, and analyzing mechanical assembly sequences. Propositional temporal logic of Manna and Pneuli is the assertion language used for representing and analyzing all constraints or conditions that assembly sequences must satisfy. The generalization of the existing representations(More)
The introduction of state equation model of the electrical machine based on direct and quadrature axes variables has paved the way for powerful control theories to be brought to bear on the problem of control of electric machines. Exact linearization has been applied to the control of permanent magnet synchronous motor (PMSM). In this paper, application of(More)
For a nonlinear system with a control input, a generalized form of the homological equation can be formulated to reduce the system to its normal form. In this paper, it has been shown that for a linearly controllable system with an appropriate choice of state feedback, the generalized homological equation can be solved to give an explicit solution, of a(More)
In this paper, a quadratic linearisation technique based on Poincare's work is proposed. Unlike the existing feedback linearisation techniques, the proposed method does not introduce singularities in the system. Moreover, we make the quadratic linearisation for a class of systems complete in the sense that higher order terms are not left behind in the(More)
