Abstract

An innovative dual version of the direct adaptive pole-placement controller (APPC) is designed, using bicriterial optimization. A new performance index for control optimization of adaptive pole-placement systems is suggested. In contrast to the well-known direct APPC, based on the certainty equivalence (CE) assumption, the accuracy of the parameter estimation and necessity of an optimal excitation signal are taken into account in the presented controller design. It is emphasized that the new controller provides improved control performance, especially at the commencement of adaptation. Simulated examples are used to demonstrate the potential and superiority of the designed controller over the original APPC.

    Solving the optimization problem in the adaptive dual control for a desirable control law is not trivial, and this difficulty promoted the development of suboptimal or modified adaptive dual control. E.g., the innovation dual control (IDC) [28] introduced a novel cost function with two conflicting parts, which transmits two optimization problems to a single one; the bicriterial dual control (BDC) [29] derived dual control law from the estimation criterion within a specific region, which is asymmetrically distributed around the caution control. Due to its advantages in tackling uncertainties, the principle of adaptive dual control has been widely applied in diversities of control strategies, such as linear quadratic Gaussian control [30], model predictive control [31,32], neural network based control [33], and control based on reinforcement learning [34], to reduce the system uncertainty and improve the control performance during phases of rapid adaptation.

    It was shown that the dual controller led to a significant improvement in the control performance over the entire processing time in comparison with a standard CE controller. Filatov, Keuchel, and Unbehauen (1996) benchmarked a bicriterial EDC controller (Filatov & Unbehauen, 1995; Filatov, Unbehauen, & Keuchel, 1997) against a CE controller for the roll angle control of a laboratory-scale, vertical-takeoff airplane with unstable and nonminimum phase dynamics. The MPC strategy with integrated OED in Heirung et al. (2015) was extended for linear multi-input multi-output systems, and was implemented on a laboratory-scale continuously-stirred tank heater process (Kumar, Heirung, Patwardhan, & Foss, 2015).
