Unknown asymmetric matrix solver pcg
WebDec 1, 2007 · The PCG method is a very powerful indirect method for solving a symmetric positive matrix [15]. To apply the PCG solver, the asymmetric equations were first … WebThis paper proposes an approximate optimal curve-path-tracking control algorithm for partially unknown nonlinear systems subject to asymmetric control input constraints. Firstly, the problem is simplified by introducing a feedforward control law, and a dedicated design for optimal control with asymmetric input constraints is provided by redesigning the …
