  • Weigh feeding system with self-tuning stochastic control and weight and actuator measurements
    Patent number: 4954975
    Abstract: A weigh feeding system using a stochastic controller wherein the weight of material and the position of a material discharge actuator are sensed, and an estimate of the mass flow state of the material being discharged is created by use of a Kalman filter process. Plant noise processes and measurement noise processes, which affect the measured weight and actuator position signal, are modeled as stochastic processes and are used, in combination with the sensed weight and actuator position signals, to calculate the estimated mass flow state. The noise models are modified to account for disturbances. The estimated mass flow state signal is used to calculate a motor feedback signal which, in turn, is used to control the speed of the discharge apparatus. In this manner, the mass flow of the material actually being discharged is driven to a desired mass flow with minimum error variance in the presence of unavoidable plant and measurement noise.

  • Weigh feeding system with stochastic control
    Patent number: 4775949
    Abstract: A weigh feeding system using a stochastic controller wherein the weight of material is sensed, and an estimate of the mass flow state of the material being discharged is created by use of a Kalman filter process. Plant noise processes and measurement noise processes, which affect the measured weight signal, are modeled as stochastic processes and are used, in combination with the sensed weight signal, to calculate the estimated mass flow state. The noise model is modified to account for severe disturbances. The estimated mass flow state signal is used to calculate a motor feedback signal which, in turn, is used to control the speed of the discharge apparatus. In this manner, the mass flow of the material actually being discharged is driven to a desired mass flow with minimum error variance in the presence of unavoidable plant and measurement noise.
