| Abstract: | This paper proposes a satisfactory optimization method for the multivariable control system with multi-parameters and multi-objectives. By designing satisfactory rate functions of performance criterions and comprehensive satisfactory rate functions of the system, satisfactory optimization model of multivariable control system is constructed, in which satisfactory design of performance criterions and optimization of controller parameters are considered together. Then, the satisfactory optimization design procedure is given in detail by using improved genetic algorithm. Simulation results show that better performances can be obtained with satisfactory optimization method than those with traditional methods, indicating that the method introduced is effective and practical. |
