摘 要：正The paper deals with the simulation of batch crystallization processes and their crystal size distribution controllability by temperature *** dynamic of crystallization processes under consideration is governed by hyperbolic partial differential *** propose simulating the processes of one size variable using the method of *** turns out that the method of characteristics has no numerical diffusion as compared to the finite difference *** a desired crystal size distribution,we investigate its reachability from the null initial condition（*** seeding） by controlling the temperature. Some checkable criterion is established to determine if a desired crystal size distribution is *** it is reachable, an admissible temperature control is constructed to steer the states to the desired distribution in finite *** construction is developed based on the discretized model and applied for the original model described by partial differential *** ensure a desirable distribution to be reached,we add an output feedback control law to correct possible errors given rise to by uncertainty of parameters.
