An improved included angle division method for multimodel control of Hammerstein systems
An improved included angle division method is proposed for Hammerstein systems. In this division method, nonlinearity of the system is taken into account to distribute gridding points, so distribution is more reasonable and computation load in division is reduced greatly. Based on the division result, a multimodel predictive controller is designed to overcome the drawbacks of the common nonlinearity inversion control method for Hammerstein systems.
