Efflux ratio is an important variable affecting the uniformity and characteristics of the final paper. Therefore, it is important for medium and high-speed paper machines to have their efflux ratio under control. This article presents the employment of CAD technique for designing a feedforward control system, a cascade control system and their controller's mathematical models for controlling efflux ratio. The performance of the paper machine wet end with efflux ratio control systems are simulated by Advanced...

Efflux ratio is an important variable affecting the uniformity and characteristics of the final paper. Therefore, it is important for medium and high-speed paper machines to have their efflux ratio under control. This article presents the employment of CAD technique for designing a feedforward control system, a cascade control system and their controller's mathematical models for controlling efflux ratio. The performance of the paper machine wet end with efflux ratio control systems are simulated by Advanced Continuous Simulation Language (ACSL). Results of simulation are analysed and compared.It is found that both feedforward control system and cascade control system' presented in this article are capable of overcoming disturbances to give efficient control responses, with feedforward control better off than cascade control.
