On Improving Control of Turbo Shaft Engine Acceleration

The traditional PID (Proportional-Integral-Differential) method, when used to control turbo shaft engine acceleration gives dynamic performance that is, in our opinion, not quite satisfactory. This paper aims to achieve better dynamic performance. By replacing PID method with SQP (Sequential Quadratic Programming) method, we can achieve better control of turbo shaft engine acceleration. When applying SQP method to turbo shaft engine acceleration, care should be taken to establish properly constraint functions (subsection 2.1) and objective function (subsection 2.2). Simulation results, as shown in Figs.1 through 6, prove preliminarily that SQP method can indeed give good optimal control and improve turbo shaft engine dynamic performance.
