A new strategy involving the cancellation of system poles and controller zeros is proposed for the indirect adaptive pole-assignment controllers. The resulting controllers can be implemented without solving simultaneous equations. A new method of eliminating the offset due to reference input without an explicit integrator is also proposed. The new strategies can be applied to pole assignment controllers of both general-feedback structure and error-driven structure. The results obtained from the simulations and trials on a stirred tank process verify that the controllers work well.
