The first type of control system is a system with nonlinear input-output relationship. A new finite-time H∞ controller design method is proposed by combining finite-time stable control design method with H∞ control theory. The effectiveness and superiority of the proposed design method are demonstrated by comparing the simulation results with the performance of traditional controller design methods.The second type of control system is a linear system with time delay. The generalized finite-time H∞ control design method is mainly used to study this type of problem. This method mainly uses the solution of the Riccati equation to design a generalized finite-time H∞ controller that satisfies constraints. The simulation results show that the controller can achieve accurate control effects in a limited time.Keywords: finite-time stable control, H∞ control, nonlinear system, time-delay system, Riccati equation.
