The paper presents a proposed method with new algorithms written inMatlab language to find the numerical solution of nth order state-space equations(SSE's) of nonlinear continuous-time control system using Hûta method. The statespaceequation is the modern representation to analysis linear and nonlinearcontinuous time invariant and time varying system. It was treated numerically tothe single-input-single-output (SISO) time invariant and time varying systems aswell as multiple-input-multiple-output (MIMO) time invariant and time varyingsystems by using sixth-order-eight-stage Hûta method. We show that it is possibleto find the output values of nonlinear state-space model using Hûta method.Finally, comparison between the numerical and exact results has been given withillustrative figures for some test examples for solving different types of nonlinearstate-space equations using Hûta method for conciliated the accuracy of the resultsof the proposed method.
